Nothing reveals a billionaire mindset quite like their spending habits. After all, to earn serious money, you first need to know why you want it. At first glance, it looks like madness - mushrooms on the orbit, banana art, tigers in Lambos. Crypto's wealthiest often seem to turn spreadsheets into spectacle - burning millions on stunts that feel more absurd than strategic. But what if that chaos is the clue? Maybe how they spend their wealth says more about how they earned it - and how they think.

About a month ago, I shared how my internship and final semester project came together perfectly, giving me the chance to dive into Laravel while building a platform to reduce food waste by connecting businesses with surplus food. I’m excited to say we’re nearly done! Over the past few weeks, our team has been polishing the app — fixing bugs, refining the user experience, and preparing for launch. The backend and database will be hosted soon, making the platform live and accessible. Looking Back at the Tech Stack: Backend: PHP Laravel — my internship experience gave me a strong foundation here, and I’ve deepened my understanding of scalable architecture, API development, and ORM relationships. Frontend: React — my teammate has built a clean, responsive UI that complements the functionality we’ve worked hard to develop on the backend, resulting in a seamless user experience across the platform. Database: MySQL — we designed the schema to handle complex relationships efficiently, especially for managing users, food listings, and organization profiles. This project has been both technically and personally rewarding. We’ve approached it like a real-world product, learning through every challenge. What’s Next: Deploying the backend and database online Final usability testing Gathering feedback for improvements If you’ve worked on something similar or have any tips for hosting and scaling Laravel apps, I’d love to connect and learn from your experience. Thanks for following along — more updates soon!  ( 3 min )

What breaking AI workflows taught me about the future of engineering. In traditional software development, when something breaks, you look at the logs. You dig into the stack trace, inspect variables, step through the debugger, isolate the bug. In AI-powered applications, that world is gone. When an LLM fails, there’s often no crash, no error, and no stack trace. Just a subtly wrong response. A hallucination. A weird behavior that’s technically correct but totally wrong for your user. Debugging becomes conversational. And that changes everything. In our product Linkeme, we rely on prompts to: Generate social media content Choose relevant CTAs Compose visual overlays And yet, some of the most frustrating bugs we faced early on didn’t come from bad code — but from poorly constructed prompts.…  ( 4 min )

Unlike traditional hardware firewalls that protect at the network edge, a software firewall is installed directly on host machines, virtual instances, or endpoints. Its primary job is to inspect, filter, and manage data traffic based on customized security rules. This digital guardian monitors both inbound and outbound connections, blocking suspicious activity and allowing only trusted communication to flow through. Whether it's a server, laptop, or cloud-based instance, a software firewall ensures that devices remain guarded—regardless of where they’re located. Software firewalls function by analyzing data packets using intelligent filtering techniques. They offer controls such as application-level monitoring, port and IP address restrictions, and real-time traffic evaluation. Administrat…  ( 4 min )

The recipe first Avoid using ObjectId Type for Ambiguous Typing System Across Tiers by favoring Strings instead. This will result in simpler backend types and DTOs that are reusable at the front end without requiring any special tools. The main disadvantage of this approach is a slight decrease in performance, as strings are larger than ObjectIds and can impact fast sorting operations. This scenario originated from a real application. It seems we followed the basic rules in different steps but ultimately failed. It would be great if we had changed the architecture at the start. Our application has a stack consisting of NestJS, Angular, and Mongoose, all written in TypeScript. We successfully implemented reusing typings across tiers, but it appeared complicated. Each tier had its own typing system, which could have been optimized. A clue to the problem is that the type of the primary field _id is ObjectId, a complex type present only on the backend. This made it unnatural for it to be used on both the frontend and backend. Some tools were implemented to reuse these types on ObjectId. New UI types were created, which seemed to improve the application's typing system. However, the application became convoluted, and we didn't want to research the case of using plain string IDs because we thought our approach was correct and it worked everywhere except for MeteorJS projects. If we refused to use the ObjectId type, we could eliminate the need for these tools, new UI types, and even DTOs that work on both frontend and backend. To test this idea, we created a separate project where I implemented the concept. The only disadvantage is the potential impact on MongoDB performance, which I couldn't measure. Additionally, we experimented with meaningful primary IDs where demanded custom solutions where string type is demanded.  ( 3 min )

Hi, I'm the developer of JavaFactory — a code generation tool that automates Java development using LLMs. Most AI code tools I've tried (like Cursor, Copilot, etc.) produce general-purpose code that's often unusable in real-world projects. They might write code quickly, but the result is: unpredictable, hard to maintain, and often completely wrong ( not usable ). So I built something different: A tool where I can explicitly define patterns and precisely control which classes are referenced. Yes, it takes some upfront work to define the rules. But the result? → Code that's testable, maintainable, and consistent with your actual architecture. In this demo, 400 lines of Java code (including tests) were generated in 20 seconds. All tests passed without manual edits. If you're tired of copy-pasting boilerplate and want AI that respects your structure — give this a try. 🔗 GitHub: link JetBrains Marketplace  ( 3 min )

Introduction In TypeScript, you can define custom shapes using type aliases or interface. But when it comes to choosing between them, many developers ask: "TypeScript Type vs Interface?" The answer is increasingly clear: use type. While both share similarities, type offers more flexibility, supports complex patterns, and aligns better with modern TypeScript and frameworks. In this guide, you'll learn the differences, strengths, and why type is the better default. Both type and interface define object shapes or function signatures: // Using type type Point = { x: number; y: number }; type SetPoint = (x: number, y: number) => void; // Using interface interface Point { x: number; y: number } interface SetPoint { (x: number, y: number): void } They look and behave similarly here, but the d…  ( 5 min )

In the ever-evolving world of software development, a seismic shift is underway. Developers, once primarily focused on writing code and building applications, are increasingly stepping into a new role: that of AI workflow designers. This transformation is not driven by a deliberate career pivot but by the rapid integration of artificial intelligence (AI) tools into the development process. These tools are reshaping how software is built, tested, and deployed, turning developers into "accidental architects" who orchestrate complex AI-driven workflows rather than solely crafting lines of code.

You may remember how much did others tell you to write your tests first, see them fail, and only write your production code after that? It's one of the craziest waste of time in software development, but not for the reasons you may think.

So, have you just accepted the implied message that if you don't write your tests first, your code will be untestable? Does it feel like you always need to make an extra effort to turn your code testable but you're not exactly sure why? Turns out, long story short, what makes code untestable is side effects.

We'll walk through the process step-by-step, emphasizing browser-first approach to achieve optimal performance and a smaller code footprint by making the most of native browser APIs and features. In this article, we'll build a CSS animated, React-powered Carousel component. Carousels are like the circus of UIs: they spin, dazzle, and keep users engaged with rotating content. Whether it’s a kid’s amusement park or a digital dashboard, rotation isn’t just motion, it’s magic. This video demonstrates a model of our component. We’ll create a real (or at least, believable) image carousel that rotates smoothly, always keeping one slide fully visible. This is the HTML code we w…  ( 9 min )

What Is Rate Limiting & Why It Matters webdev api security scalability architecture Rate limiting is about controlling how often a client can hit your app or API. It helps prevent abuse, reduce server load, and ensure fair access for everyone. Without it, one bad actor (or even an accidental loop) can overload your system. Every time a client makes a request, your server tracks how many requests they’ve made within a defined time window. If they exceed that limit, the server denies further requests — usually with a 429 Too Many Requests response. Clients can make a certain number of requests per fixed time period (e.g. 100 per minute). Simple but can lead to burst traffic at the start of each window. Spreads the request limit more smoothly over time. Prevents sudden spikes that fixe…  ( 4 min )

A Technical Evaluation of Milvus and Chroma DB In the rapidly evolving AI infrastructure landscape, vector databases have emerged as critical components for handling high-dimensional data. This analysis examines two prominent contenders—Milvus and Chroma DB—through the lens of enterprise readiness and developer experience, providing actionable insights for technical teams. Architectural Philosophy & Deployment Performance Benchmarks Milvus achieves 15,000 QPS on 768D vectors with 8ms p95 latency (32-node cluster) Chroma DB manages 2,300 QPS at 28ms latency (standalone instance) The gap widens with complex operations: Milvus' proprietary ANNS algorithms outperform Chroma's FAISS-based implementation by 40% in recall accuracy at 1M+ scale. However, Chroma's memory-mapped indexes demonstrate advantages for frequent schema modifications during development cycles. Ecosystem Integration Native PyTorch/TensorFlow data loaders Automated versioning for vector snapshots Grafana/Prometheus monitoring templates Chroma prioritizes LLM workflows with: LangChain integration out-of-the-box OpenAI embedding API compatibility Dynamic metadata filtering optimized for RAG pipelines Enterprise Readiness Cost Considerations Technical Recommendation Both platforms continue evolving—Milvus recently added GPU-accelerated indexing, while Chroma introduced hybrid scalar-vector search in Q2 2024. Technical leaders should evaluate these systems through the prism of their operational maturity and scalability requirements rather than seeking a universal solution. Note: All benchmark data reflects testing on AWS c6i.8xlarge instances with 500M 512D vectors unless otherwise specified.  ( 4 min )

Today, I dived into the world of CSS transitions, and I was excited to see how a small piece of code can make a website feel more smooth and interactive. In this post, I’ll share what I learned and how transitions work in CSS. CSS transitions allow you to change property values smoothly (over a given duration) instead of instantly. For example, instead of a button changing color immediately when hovered, transitions let that color change happen gradually. Here’s the basic syntax of a CSS transition: selector { transition: property duration timing-function delay; } property: The CSS property you want to animate (e.g., background-color, width, transform) duration: How long the transition takes (e.g., 0.5s, 1s) timing-function (optional): The speed curve (e.g., ease, linear, ease-in, ease-out, ease-in-out) delay (optional): The delay before the transition starts Hover Me .btn { background-color: #4CAF50; color: white; padding: 10px 20px; border: none; transition: background-color 0.3s ease; } .btn:hover { background-color: #2E7D32; } When you hover over the button, the background color changes smoothly from green to dark green in 0.3 seconds. You can transition multiple properties like this: .box { width: 100px; height: 100px; background-color: red; transition: width 0.5s, background-color 0.3s; } .box:hover { width: 200px; background-color: blue; } Only animatable properties can be transitioned (e.g., color, background-color, transform, opacity, width, height, etc.) Use transition: all if you want all animatable properties to transition — but use it carefully, as it can affect performance. Combine transitions with pseudo-classes like :hover, :focus, or :active for better interactivity. Learning CSS transitions opened my eyes to how much they can improve the user experience of a website. They're simple to use but make a big impact visually. I’m excited to explore more about animations using @keyframes and the animation property next!  ( 4 min )

Hello together, During my search with the AI Perplexity, I did not find good results to determine how to specify a number as a parameter or as a variable in Uniface. Although there is Uniface documentation [1] on this, it was not found. I do not understand why the AI cannot find the definition of a number in Uniface, even though there is a source for this. To make the best of it, I decided to write down my thoughts here. I do not consider myself a Uniface Senior or some kind of specialist in Uniface but rather as a beginner in this programming language. Regarding the question of how to represent a number in Uniface, the answer is the following: params Taken from the documentation of Uniface.

Is SaaS Really Dead? Several months ago, the internet was abuzz with the Microsoft CEO Satya Nadella saying, “SaaS is dead.” The conversation started with a question from Bill Gurley about whether Satya was worried that newer startups are building applications with an AI-first approach, which could obfuscate traditional infrastructure like Excel or CRM. Here is Satya’s response: I think, the notion that business applications exist, that's probably where they'll all collapse, right in the agent era because if you think about it, right, they are essentially CRUD databases with a bunch of business logic. The business logic is all going to these agents, and these agents are going to be multi repo CRUD Some people might assume he suggested that AI agents could or would replace SaaS. Howe…  ( 9 min )

In the world of data, change is the only constant. Over the last few decades, SQL (Structured Query Language) has reigned supreme as the go-to language for managing relational databases. Then came NoSQL, challenging the traditional norms with its flexibility and scalability. But today, a new player is emerging quietly yet powerfully: NewSQL. So, is SQL really dying? Is NoSQL losing its charm? And what exactly is NewSQL? Let’s break it down. The Era of SQL: A Quick Recap But as data exploded in volume, velocity, and variety — thanks to social media, IoT, and mobile apps — traditional SQL databases began to struggle with horizontal scalability and flexible schemas. The Rise and Struggles of NoSQL Schema-less design — ideal for unstructured or semi-structured data Lack of ACID guarantees The Death of SQL? The Silent Rise of NewSQL by Abhishek Shakya 🔑 Key Features of NewSQL Databases: Cloud-Native Architecture Real-Time Performance Data Integrity at Scale Simplified DevOps Real-World Use Cases Traditional SQL systems are struggling to keep up with modern demands. NoSQL tried to fill the gap but fell short in consistency and relational data handling. NewSQL is emerging as a modern solution, blending the best of both worlds: the familiarity of SQL and the power of NoSQL. The future isn’t SQL vs. NoSQL. It’s NewSQL — scalable, reliable, and SQL-compatible. If you’re building high-scale, mission-critical apps today, NewSQL might just be the quiet revolution you didn’t know you needed. ✅ Key Takeaways SQL is aging, but not obsolete. NoSQL brought scalability but lacked consistency. NewSQL offers the scalability of NoSQL with the reliability of SQL. NewSQL is powering modern, distributed, cloud-native applications.  ( 5 min )

Hal ini terjadi karena AI makin pintar dan makin meresap ke dalam kehidupan sehari-hari. Fenomena ini penting untuk dipahami oleh siapa saja yang menggunakan teknologi digital—mulai dari pelajar, pekerja, hingga pebisnis—karena AI kini sangat memengaruhi cara kita hidup dan bekerja. Kenapa AI bisa makin pintar? bagaimana AI bisa tahu apa yang kita suka? Dampaknya pada kehidupan kita sangat beragam. Contohnya, AI mungkin salah memprediksi preferensi kita, sehingga kita kehilangan kesempatan mendapatkan informasi penting. Seringkali, kita tidak sadar bahwa keputusan sehari-hari sudah dipengaruhi oleh AI karena prosesnya berjalan secara otomatis dan tersembunyi. Lalu, bagaimana kita menyikapi perkembangan ini supaya AI tidak merugikan? Pertama, kita perlu memahami bagaimana AI bekerja dan data apa saja yang kita bagikan. Kedua, gunakan fitur privasi yang tersedia di aplikasi dan perangkat digital. Ketiga, selalu kritis terhadap rekomendasi dan informasi yang diberikan oleh AI. Misalnya, jangan langsung percaya iklan yang muncul, tetapi cek dulu keasliannya agar tidak mudah tertipu. Dengan edukasi dan kesadaran yang baik, kita bisa lebih aman dan cerdas dalam memanfaatkan teknologi AI. Bayangkan kamu sedang mencari pekerjaan, dan platform rekrutmen berbasis AI merekomendasikan pekerjaan yang tidak sesuai dengan minatmu hanya berdasarkan data lama yang pernah kamu input. Apakah kamu akan mengikuti saran itu begitu saja? * Ini contoh nyata bagaimana AI yang makin meresap bisa memengaruhi keputusan penting dalam hidup kita. Oleh karena itu, yuk mulai kenali AI yang kamu gunakan, atur privasi dengan baik, dan jangan takut bertanya serta belajar supaya AI benar-benar menjadi alat yang membantu, bukan justru mengatur hidup kita tanpa kita sadari.  ( 4 min )

If you’ve seen this in your console: “Access to fetch at ‘https://api.example.com’ from origin ‘https://yourapp.com’ has been blocked by CORS policy…” You’re not alone. Let’s dive into what CORS is, why it exists, and how to fix it. CORS? CORS (Cross-Origin Resource Sharing) is a browser-enforced security feature that prevents your frontend app (served from one origin) from accessing resources from another origin unless explicitly allowed by the server. This behavior stems from the Same-Origin Policy, which is designed to help prevent cross-site attacks. How CORS Works When your frontend makes a request to another origin, the browser sends an Origin header: Origin: https://myapp.com If the server responds with: Access-Control-Allow-Origin: https://myapp.com Preflight Requests For requests using methods like POST, PUT, or custom headers, the browser sends a preflight OPTIONS request to check if it’s safe. If the server doesn’t respond correctly, the browser cancels the actual request. Backend Config: Enabling CORS Here’s how to configure CORS in common backend frameworks: 🟢 Express.js const cors = require('cors'); 🐍 FastAPI app.add_middleware( https://myapp.com"], "], "], ❗ Common CORS Issues ❌ Missing Access-Control-Allow-Origin header ❌ Wildcard origin (*) used with credentials ❌ Server doesn’t respond to OPTIONS preflight 🧠 Dev Tips Use tools like http-proxy-middleware or Vite’s proxy config during local development. Never disable CORS in production — configure it properly. ✅ Final Thoughts CORS is not a bug — it’s a feature 🔐 Understanding how it works makes you a more confident full-stack developer and prevents hours of frustrating debugging. 💡 Got a CORS horror story or a helpful trick?

Now imagine that instead of a shared thermostat or central lighting control, every room make…  ( 5 min )

Article originally published here (image doesn't work well here) : https://alsohelp.com/blog/background-jobs-in-rails-8-are-delightful There's one thing I forgot to mention about my Rails 8 opinion last time : it's how background jobs are handled in Rails 8. Here's what it looks like on my current project : (image) Most web frameworks completely underestimate how background jobs are valuable. Honestly I always need a way to handle background jobs, on every new web project. Forgot password email ? => background task to send the email Clean image asynchronously ? => background task to clean the image And so on. IMHO A good way go see if a framework is mature enough is "are background jobs already included from day 1". Why it is so good with Rails 8? Because you don't have to care about : it's already included. From what I've read, it's not possible with other frameworks - outside Laravel. The Database is already backed The Dashboard is already included (!) And, of course, it's damn easy to hook any kind of job inside the framework itself. All I had to do is to protect the route, so that only the admin can view it. You don't have to care about the JS/CSS, because as long as you keep "propshaft" as gem, it will work. The beauty (again) is that I don't use propshaft myself. I use Vite. This is Rails deep integration : even if you don't use the default frontend management, external gem will work with your product. Of course "background jobs" means "take another thread than the one of the web server". So there's a tiny configuration locally (Thank you Matt Brictson for your bin/dev Rails 8 shine not only for the things previously mentionned, but also thanks to mission control. It gives you very elegant, monitor-able background jobs, right from day one, with full support and upgrades of the Rails maintainers. Close from silver bullet ;)  ( 4 min )

TypeScript - sounds familiar to another coding language called JavaScript, right? Well, it's a language based on JavaScript; the only difference is that it focuses on type safety.

I no longer think you should learn to code. Amjad Masad (CEO of Repit) I’ve been coding for about 16 years and working professionally for over a decade. After months of testing AI-assisted tools and “vibe coding” in early 2025, I can confidently say: that statement couldn’t be further from the truth. Sure, LLMs have pulled off some amazing things. And if you don’t know what it really takes to build working software, it’s easy to think the old way is now obsolete. But trust me, it’s not. Let’s take a look at things that have happened before, because this is not the first time we face a statement like this; back in the late 50’s - early 60’s COBOL emerged stating that it would allow people without traditional programming backgrounds ( like business professionals, managers, and analysts ) …  ( 10 min )

Concurrency VS Synchronization Synchronous code When code executes line by line in order, one thing at a time is called synchronous. It is simple, but sometimes might not be very efficient. func main() { // block 1 x := 10 x++ fmt.Printf("x = %d", x) // block 2 y := 20 y-- fmt.Printf("y = %d", y) } Check the code blocks in the above example. As you can see, the code lines in block 1 should execute in order. The code lines in block 2 should also execute line by line. But blocks 1 and 2 have no dependency on each other. So, we can run them separately on two CPU cores. This is called running in Parallel. It increases efficiency. In Golang, it is easy to write concurrent code. func main() { // some code go funcName() // rest of the co…  ( 6 min )

Problem description & analysis: The ID field of a certain database table is used for sorting, the logic field is used for conditional judgment, and val is used for segmented accumulation. Task: Now we need to add a calculated column output. When logic==true, output is set to 1. Otherwise, output is accumulated and the value is the output of the previous row + val. SQL： with table1 as ( SELECT *, countif(logic) over win1 as logic_run FROM example_data window win1 as (order by id rows between unbounded preceding and current row) ) SELECT *, sum(val) over win2 as sum_over, sum(if(logic,1,val)) over win2 as output from table1 window win2 as (partition by logic_run order by id rows between unbounded preceding and current row) SQL requires multiple window functions and subqueries to indirectly implement cumulative calculations, which is cumbersome in terms of code. SPL: SPL provides syntax of relative positions that allows for direct accumulation. ✍🏻 Try.DEMO A1： Load data.

1. Background and Motivation Although Google Guava’s EventBus is already quite convenient, I wanted to build something more extensible — a component that not only functions as an EventBus but also supports delayed events out of the box. While exploring the Apache DolphinScheduler project, I found its built-in eventbus component to be a well-written and efficient solution. It inspired me to extract and adapt it for use in our own business systems. Thanks to DolphinScheduler’s open-source nature, this component can now be conveniently reused with minimal overhead. Let’s walk through how to extract it and run a working demo. First, we define a base interface for all events: public interface IEvent { } To support delayed execution, we introduce an abstract class AbstractDelayEvent that exte…  ( 5 min )

Em programação, um dicionário (também chamado de mapa ou hashmap) é uma estrutura de dados que armazena dados em pares de chave-valor, onde as chaves são usadas para acessar os valores. É como uma lista onde os elementos são acessados por nomes (chaves) em vez de índices numéricos. As chaves do dicionário são usadas como índices para localizar o valor associado. Ao invés de percorrer a coleção inteira para encontrar um valor, o dicionário usa a chave para calcular um índice na tabela hash. Essa chave é passada para uma função hash, que gera um valor numérico (o índice na tabela hash). Para exemplificar, vamos armazenar o valor do quilograma de cada fruta dentro do dicionário. Tabela hash: Em JavaScript, o objeto Map armazena pares chave-valor preservando a ordem de inserção e aceita qu…  ( 5 min )

Pseudo-element yang Wajib Diketahui Pseudo-element secara bahasa artinya Element Semu, alias element yang samar atau tersembunyi. Pada beberapa elemen HTML ada yang membawa elemen semu seperti elemen input yang membawa elemen semu placeholder. Kalau kita memberikan styel color ke input, maka style tersebut akan diterapkan ke hasil inputan kita dan bukan ke placeholder. Disini lah peran pseudo-element sebagai selector ke placeholder. Pseudo-element ciri khasnya diawali dengan titik dua dua di depan. Jadi untuk placeholder selectornya menjadi ::placeholder.

Closures in JavaScript occur when a function retains access to variables from its lexical scope, even after the outer function has finished execution. This allows functions to "remember" values and maintain state. 🔹 Simple Example: function outerFunction() { let counter = 0; // Local variable return function innerFunction() { counter++; // Inner function remembers 'counter' console.log(counter); }; } const increment = outerFunction(); // Returns innerFunction increment(); // 1 increment(); // 2 increment(); // 3 🔹 Explanation: outerFunction() defines a local variable (counter). innerFunction() modifies counter, but the outer function has already executed! However, innerFunction() retains access to counter due to closure behavior. Each call to increment() updates the retained counter, demonstrating persistent state. Closures are useful for encapsulation, maintaining private variables, and creating efficient event handlers. 🚀  ( 3 min )

1. Why Build a Message Queue from Scratch? Message queues are the unsung heroes of distributed systems—think of them as traffic cops directing data between services. They decouple apps, handle async tasks, and smooth out traffic spikes. NSQ, a lightweight, Go-based queue from Bitly, caught my eye for its simplicity and speed, making it perfect for small-to-medium projects. So why rebuild it? Two reasons: Learning by Doing: Nothing beats rolling up your sleeves to grok how queues tick. Customization: Need priority messages or a leaner persistence layer? DIY lets you tweak it your way. This tutorial walks you through coding an NSQ-inspired message queue in Go. It’s aimed at devs with 1-2 years of Go experience—folks comfy with goroutines and channels but itching to tackle distributed s…  ( 9 min )

The $330 million attack: A stark reminder of social engineering’s power A major crypto theft has sent shockwaves through the industry, with $330 million worth of Bitcoin (BTC) stolen. Experts say this was a social engineering attack and not a technical hack.  Investigations led by blockchain analyst ZachXBT suggest the victim was an elderly US citizen who was manipulated into granting access to their crypto wallet. On April 28, 2025, ZachXBT detected a suspicious transfer of 3,520 BTC, worth $330.7 million.  The stolen BTC was quickly laundered through more than six instant exchanges and converted into the privacy-oriented cryptocurrency Monero (XMR). Onchain analysis shows the victim had held over 3,000 BTC since 2017, with no previous record of s…

Genesis has launched a pair of lawsuits against its parent company, Digital Currency Group (DCG), and its CEO, Barry Silbert, accusing them of fraud, reckless mismanagement and siphoning more than a billion dollars in value from the now-bankrupt crypto lender. On May 19, the Delaware Court of Chancery unsealed a complaint detailing how DCG allegedly used Genesis as a corporate ATM, draining funds through self-serving loans and concealed transfers while presenting a false image of financial health. Through their court-appointed Litigation Oversight Committee (LOC), Genesis creditors claim that over a million digital coins — worth about $2.1 billion — were funneled away, even as Genesis edged toward collapse. As per the complaint, Genesis creditors are still owed around $2.2 billion worth of…

US President Donald Trump has signed a bill criminalizing nonconsensual artificial intelligence-generated deepfake porn, which also requires websites to take down any illicit images within 48 hours. Trump signed the bill into law on May 19, known as the TAKE IT DOWN Act, an acronym for Tools to Address Known Exploitation by Immobilizing Technological Deepfakes on Websites and Networks. The bill, backed by first lady Melania Trump, makes it a federal crime to publish, or threaten to publish, nonconsensual intimate images, including deepfakes, of adults or minors with the intent to harm or harass them. Penalties range from fines to prison. Source: Melania Trump Websites, online services, or apps must remove illegal content within 48 hours and establish a takedown process. Trump said in remar…

Shares in the Indonesian fintech firm DigiAsia Corp nearly doubled after the company said it plans to raise $100 million to seed its first of many Bitcoin buys. The Jakarta-based Nasdaq-listed company said on May 19 that its board of directors approved creating a Bitcoin (BTC) “treasury reserve” and it was “committing up to 50% of any net profits generated to fund the acquisition of BTC.” DigiAsia said it was also “actively exploring a capital raise of up to US$100 million” to kickstart its Bitcoin holdings and would look to earn yield on its holdings through means like lending and staking. DigiAsia said it had “initiated discussions with regulated partners” on yield strategies and managing its planned Bitcoin holdings. The company added that it was also assessing whether to offer conver…

The US Securities and Exchange Commission’s sole Democratic Commissioner has said the agency is “playing a game of regulatory Jenga” with its approach to the crypto industry and market regulation under the Trump administration. In May 19 remarks at the SEC Speaks event, Commissioner Caroline Crenshaw cautioned against what she described as a dangerous dismantling of “discrete but interrelated rules” on crypto and the wider market. She likened market stability to a “Jenga tower” that the agency’s rules had “carefully developed over the years,” which could topple if some rules were removed. In addition to a lamentable loss of staff, Crenshaw said the SEC has used staff guidance to effectively reverse rules without proper analysis or public comment, particularly around crypto “Our statements…

Crypto exchange Binance has asked a US federal judge to send all members of a class-action lawsuit alleging it sold securities to arbitration, arguing that the group waived their ability to form a class action under the company’s terms. The exchange said in a May 16 filing to a New York federal court that its terms of service, which it claimed the class group agreed to, has a clause that users agree to arbitrate all claims, along with a clause preventing users from launching class actions against the crypto exchange. “The Court should hold that Plaintiffs are required to arbitrate claims that accrued after Feb. 20, 2019, even if the Court adheres to its initial decision as to claims that accrued before then and that the class-action waiver in the 2019 Terms of Use is enforceable for all of…

Jamie Dimon, the CEO of JPMorgan, said his bank will soon allow its clients to buy Bitcoin, but it won’t custody the cryptocurrency. “We are going to allow you to buy it,” Dimon said at JPMorgan’s annual investor day on May 19. “We’re not going to custody it. We’re going to put it in statements for clients.” CNBC reported that Dimon also remarked on his long-held skepticism about crypto assets, pointing to their use in money laundering, sex trafficking and terrorism. “I don’t think you should smoke, but I defend your right to smoke. I defend your right to buy Bitcoin,” he said. Michael Saylor comments on Dimon’s announcement. Source: Michael Saylor JPMorgan will offer clients access to Bitcoin (BTC) exchange-traded funds (ETFs), CNBC reported, citing sources familiar with the situation. Until now, the firm has limited its crypto exposure primarily to futures-based products, not direct ownership of digital assets. Related: Morgan Stanley advisers can officially pitch Bitcoin ETFs JPMorgan rival Morgan Stanley has also moved to offer spot Bitcoin ETFs to qualifying clients. Spot Bitcoin ETFs in the US have seen significant adoption, with almost $42 billion in total aggregate inflows since they launched in January 2024.  Dimon’s Bitcoin bashing history Dimon has long been skeptical of Bitcoin, labeling it a scam that he had no interest in buying in 2018 and calling it “worthless” during the 2021 crypto bull market. “I’ve always been deeply opposed to crypto, Bitcoin, etc.,” he said during a Senate Banking Committee hearing in 2023. “The only true use case for it is criminals, drug traffickers, money laundering, tax avoidance.” “If I were the government, I’d close it down,” he said. At the 2024 World Economic Forum in Davos, Switzerland, Dimon said Bitcoin “does nothing. I call it the pet rock,” which came after the asset topped $100,000 for the first time.   Magazine: Arthur Hayes $1M Bitcoin tip, altcoins ‘powerful rally’ looms: Hodler’s Digest

The US Senate has voted to advance a key stablecoin-regulating bill after Democrat Senators blocked an attempt to move the bill forward earlier in May over concerns about President Donald Trump’s sprawling crypto empire. A key procedural vote on the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed in a 66-32 vote on May 20. Several Democrats changed their votes to pass the motion to invoke cloture, which will now set the bill up for debate on the Senate floor. Republican Senator Cynthia Lummis, one of the bill’s key backers, said on May 15 that she thinks it's a “fair target” to have the GENIUS Act passed by May 26 — Memorial Day in the US. The US Senate voted 66-32 to advance debate on the GENIUS stablecoin bill. Source: US Senate The GENIUS Act was introduced on Feb. 4 by US Senator Bill Hagerty and seeks to regulate the nearly $250 billion stablecoin market — currently dominated by Tether (USDT) and Circle’s USDC (USDC). The bill requires stablecoins be fully backed, have regular security audits and approval from federal or state regulators. Only licensed entities can issue stablecoins, while algorithmic stablecoins are restricted. Several Democratic senators withdrew support for the bill on May 8, blocking a motion to move it forward, citing concerns over potential conflicts of interest involving Trump’s crypto ventures and anti-money laundering provisions. Related: Circle plans IPO but talks with Ripple, Coinbase could lead to sale: Report The bill was revised soon after to receive enough bipartisan support to proceed to a vote.

Anza, a Solana blockchain infrastructure firm spun out of Solana Labs, has proposed a new proof-of-stake consensus called Alpenglow that it claims would be “the biggest change to Solana’s core protocol” and compete with current internet infrastructure. “We believe that the release of Alpenglow will be a turning point for Solana. Alpenglow is not only a new consensus protocol, but the biggest change to Solana’s core protocol since, well, ever,” Anza’s Quentin Kniep, Kobi Sliwinski and Roger Wattenhofer said on May 19. Alpenglow consists of Votor, which processes voting transactions and block finalization logic, and Rotor, a data dissemination protocol that would replace Solana’s proof-of-history timestamping system and aim to reduce the time it takes for all nodes to agree on the network st…

Gold is often used by governments that have a large gold reserve to protect the value of their currency; that’s why it is traded on the Forex market. I chose XAUUSD due to high volume of trading together with an extensive amount of historical and real-time data available. It is also not specific to any one nation, economy, or business; rather, it is globally essential. It is more intriguing examining how the …  ( 5 min )

A gestão de projetos é, cada vez mais, um pilar técnico dentro das organizações modernas. Não adianta ter um time que domina frameworks de ponta ou uma stack atualizada se os projetos caminham sem clareza, priorização e cadência. Em muitos casos, não é a tecnologia que trava o time é a ausência de uma gestão estruturada. Empresas como o Nubank, por exemplo, entenderam desde cedo a importância de ciclos curtos e times autônomos. Ao adotar uma variação do modelo Agile, com squads multidisciplinares e foco em entregas iterativas, conseguiram escalar seus produtos mesmo utilizando uma linguagem funcional como Clojure, considerada pouco comum no mercado. Não foi apenas a escolha da linguagem que impulsionou o sucesso, mas como os projetos foram organizados para extrair o máximo do time técnico.…  ( 4 min )

Alright, folks, welcome back to the series of Model Context Protocol! In Part 2: Looking Under the Hood, we took a delightful little spelunking trip into the guts of MCP, marveling at its STDIO and SSE transport mechanisms, and even peeked at the shiny new OAuth 2.1 and Streamable HTTP features. It all looked so promising, so... functional. Well, today we're trading our hard hats for tinfoil ones. We're about to wade into the swampy, infested, and quite frankly, terrifying security landscape of MCP. If Part 2 was about how MCP works, Part 4 is about how it breaks... spectacularly. And often by design. Are Out to Get Your Data Let's be brutally honest.

Built My First React Native App — An Internal Admin Tool for Formant Took a big step forward today. I built my first React Native app — a custom internal admin tool for managing blog content and media on formant.ca, my personal dev and music studio site. It’s not public, but it’s functional and live on my own Android device. I can now post updates, write drafts, and manage media directly from my phone. Set up a fresh React Native project from scratch Built a modular interface without any templates or generators Integrated Firebase Auth and handled some runtime quirks with Hermes Deployed locally and tested the app on-device It’s the first part of a broader toolset I’m building to keep Formant fully in my hands — no third-party platforms, no content lock-in. Add image upload and edit features Expand into scheduling tools and version tracking Eventually connect it to my game data and user analytics React Native Firebase Auth Plain JavaScript Device-tested on Android This isn’t a product — it’s a personal infrastructure move.

Introduction Imagine stepping into a vast digital sandbox, ready to build anything you can dream of in a JavaScript program. In this creative space, variables are your essential building blocks and storage containers. Just like in a sandbox game where you need places to keep your tools, materials, and the scores of your players, variables in JavaScript are fundamental for holding all the information your program needs to work. They are the named boxes where you store data – from simple numbers and text to more complex structures that bring your digital world to life. In this post, we'll dig into what JavaScript variables are, why they're so crucial, how to create and name them, and how you can start using them to shape your own interactive experiences.

Azure App Service - Hidden Network Trap Dušan Knežević ・ May 19 #programming #azure #cloud #network  ( 2 min )

Introduction A few weeks ago, I was asked to investigate intermittent database connection failures affecting one of two Azure App Service instances. Both instances shared the same App Service Plan for a client, and—crucially—had been running smoothly for five weeks before these issues appeared. Interestingly, all development ("lower") environments were unaffected; only the production environments were experiencing failures. Each app used its own Azure Storage account and Azure SQL database. Both App Services were in production. The first app was failing to connect to its storage account, while the second was failing to connect to its Azure SQL database. The logs didn’t reveal anything unusual—just connection failures. Since the apps were already down, I decided to restart them, hoping a …  ( 4 min )

When working with data, we are familiar with two tools: SQL and Python. Both are important for data professionals, but they serve different purposes. So let me break down which one should you use for querying and cleaning data. Querying Data: SQL is the best. reasons is that: Optimized for Databases – SQL is built specifically for querying structured data in relational databases (PostgreSQL, MySQL, BigQuery, etc.). Faster Queries – Databases are optimized for SQL, making it much faster than Python for filtering, aggregating, and joining tables. Simple Syntax – for example when one needs sales data from last month? SQL is direct: SELECT customer_id, SUM(amount) FROM sales WHERE date >= '2024-01-01' GROUP BY customer_id; Works with big Datasets – SQL databases handle billions of rows effi…  ( 4 min )

Hello everyone, I am Zhang Handong(AlexZhang), an independent consultant and technical writer. I have been in the Rust community for ten years, and on the occasion of Rust's tenth anniversary, I want to write down my story. It may not be that extraordinary, but these ten years are where I come from today. Looking back on this journey, I see not just the evolution of a programming language, but the growth of a passionate community from nothing to something, from small to large. During these ten years, I experienced the transformation from a learner to an evangelist, and witnessed the entire process of Rust in China evolving from a niche language to gradual adoption by mainstream enterprises. This is a story about learning, sharing, challenges, and growth, and also a microcosm of Chinese dev…  ( 9 min )

Photo by Ryan Quintal on Unsplash Angular mudou e continua mudando... Antes, um componente precisava ser declarado dentro de um NgModule para "sobreviver". Agora, ele simplesmente existe — de forma autônoma. Sempre tive aquela analogia de que os componentes no Angular viviam dentro de caixas chamadas módulos, que por sua vez se encaixavam em outras caixas maiores, como o AppModule. No fim, tudo era uma grande construção de peças interconectadas, como um LEGO® bem estruturado. Mas tudo isso começou a mudar a partir da versão 14 do Angular, quando os chamados componentes autônomos (standalone) foram introduzidos como uma funcionalidade experimental. Na versão 15, essa abordagem foi estabilizada e passou a fazer parte oficial do ecossistema. E com isso vem mais uma linha de aprendizado, pois…  ( 4 min )

After the recent post by DHH about “vibe coding”, I too felt the urge to take a plunge into the “vibe coding” pool as to what it is, and why it’s appealing. The term “vibe coding” was coined by Andrej Karpathy, who was also a founding member of OpenAI. As Karpathy describes, vibe coding is when you don’t think about code, you blindly trust whatever LLMs throws at you, and you vibe your way into building something. This approach to software development is made possible by how far language models have come (like Claude Sonnet), along with the rise of AI-powered editors such as Cursor and GitHub Copilot in VS Code. Vibe coding or not, coding with AI is quickly becoming the new default. Traditional software development has a steep entry barrier. You need to learn a programming language, grasp …  ( 4 min )

We've twisted the word serverless into something vague. These days, serverless usually just means "I don't manage the infrastructure, someone else does." Which is fine. But it's also not the full picture. Because if we take the word literally (no server process to run, configure, or scale) then one database has quietly been the most serverless of all for over 20 years: SQLite. It doesn't run in the cloud. It doesn't need to connect to a remote API. It doesn't even require a boot-up process. It just works. And it's criminally underrated. Let's break this down into two flavors: This is the popular kind. You write your application and connect to a database that is fully managed by a third party. You don't worry about patching, scaling, or provisioning. Some examples: Firebase DynamoDB Neon Pl…  ( 5 min )

We are likely witnessing a quiet crisis in our technical teams. While we celebrate the productivity gains of AI tools, a more insidious process probably unfolds beneath - the surface—the systematic erosion of our fundamental technical capabilities. This is not pure speculation or technophobic fear-mongering; it is the reality playing out. The pattern is alarmingly consistent. A team adopts AI tools to enhance productivity. Initial results are impressive: faster code generation, quicker troubleshooting, more efficient documentation. Management celebrates the metrics. But something else is happening simultaneously—something few are measuring or even noticing until it's too late. Technical professionals are gradually losing their ability to think critically, solve novel problems, and understa…  ( 6 min )

Implementing a Custom Reactive Library in Vanilla JS Introduction In recent years, the demand for reactive programming paradigms has skyrocketed. Libraries and frameworks like React, Vue, and Svelte dominate the landscape, each tailored to enable developers to create dynamic user interfaces with a reactive data flow. However, the principles underlying these frameworks can be distilled into fundamentally simple concepts that can be implemented in vanilla JavaScript. This article aims to explore the implementation of a custom reactive library, examining its architecture, intricacies, and performance considerations. The roots of reactive programming can be traced back to the late 1990s and early 2000s. Initially conceptualized for event-driven applications, reactive programming u…  ( 6 min )

We all know the feeling. Suddenly your train of thought derails. You try to get back into flow, but it’s gone. Welcome to modern software development, where real productivity isn’t about working harder—it’s about working asynchronously. The Problem With Synchronous Everything Here’s the core issue: Synchronous communication assumes everyone is available at the same time. The difference is massive. If your team relies too heavily on live calls, pings, or "quick syncs," here’s what happens: Developers are constantly pulled from deep work Time zone mismatches create delays Pressure builds to be “always available” Creative thinking suffers due to fragmented focus As a developer, your job is to think clearly and build complex systems. That doesn’t happen in 15-minute chunks squeezed between Zoo…  ( 6 min )

As your cybersecurity toolkit grows, one concept becomes increasingly important—aggregation. Logs from a single server tell a story, but when you start working with networks of devices, cloud services, containers, and multiple endpoints, you quickly realize that analyzing one log file at a time is not enough. You need a way to bring those logs together, sort through the noise, and create a unified view of what is happening across your environment. That is where log aggregation comes into play. By collecting and combining log data from multiple sources, you can detect patterns, respond faster to incidents, and make informed decisions. In this article, we will explore how to build simple but effective log aggregation workflows using Python, and why it is a powerful step forward in your secur…  ( 6 min )

🚀 What is the Model Context Protocol (MCP)? The Model Context Protocol (MCP) is an open standard introduced by Anthropic that aims to simplify how AI applications—like chatbots, IDE assistants, or custom agents—connect with external tools, data sources, and systems. Before USB, connecting devices meant dealing with dozens of ports and drivers. Similarly, integrating M different AI apps with N different tools used to require M × N custom integrations—a huge development burden. MCP changes that to an M + N model: Tool creators only need to build 1 MCP server per tool App developers only need to build 1 MCP client per application 🧩 How it works MCP follows a client-server architecture: Hosts: AI applications the user interacts with (e.g., Claude, an IDE, a custom agent) Cli…  ( 4 min )

I came across The Cloud Resume Challenge by Forrest Brazeal while studying for my AWS CCP exam, and without much thought, I added the website to my bookmarks. I was certain that at some point, I would take on the challenge, as it seemed like a great opportunity to gain hands-on experience with AWS. And… I did — after passing my exam, I started working on the project. At the very beginning, I had to set up my AWS personal development environment to ensure that my account (and my wallet!) was properly protected. To do so, I decided to use AWS Organizations. I created a "root" AWS account and set up an AWS Organization with an Organizational Unit (OU) inside it. Under the OU, a new AWS account was created, and this was the account used to create any resources related to the project. At this s…  ( 5 min )

Web UX is having a moment. Not because of a new JavaScript framework (for once), but because of something much more fundamental: natural language as the interface itself. In early 2025, Microsoft introduced NLWeb, a project that brings conversational AI directly into websites via simple HTML attributes and JavaScript APIs. It's a shift that front-end developers and designers alike should be paying close attention to — because it fundamentally changes how users interact with the web. NLWeb is a Microsoft initiative designed to embed natural language interfaces directly into web experiences.

The Singleton pattern is one of the most fundamental design patterns in software engineering, and it has several practical applications in frontend development. While often debated (as overuse can lead to issues), when applied judiciously, the Singleton pattern can solve specific problems elegantly in client-side applications. A Singleton is a design pattern that restricts a class to a single instance and provides global access to that instance. In JavaScript/TypeScript terms, it ensures that no matter how many times you try to create an instance of a class, you always get the same instance. Modern frontend frameworks often use Singleton-like patterns for state management: // Redux store (typically a Singleton) import { createStore } from 'redux'; import rootReducer from './reducers'; con…  ( 5 min )

Traditional AI evaluation methods are struggling to keep pace with the rapid evolution of language models. Metrics like BLEU and ROUGE scores, which rely on deterministic measurements, fall short when assessing the creative, non-deterministic outputs of modern AI systems. Enter "LLM as a judge" — an innovative approach that uses language models themselves to evaluate AI outputs. This method harnesses the sophisticated understanding capabilities of LLMs to provide nuanced, context-aware assessments that better match the complexity of today's AI systems. Unlike conventional evaluation methods, LLM judges can adapt to varied contexts and offer detailed, qualitative feedback that more closely resembles human judgment. Language model judges function by implementing sophisticated prompt engineer…  ( 4 min )

Cloud cost breakdowns don’t have to break you. Here’s a beginner-friendly dev's guide to FinOps—fun, practical, and a little too real. You know that feeling when your cloud bill hits and you stare at it like it’s written in Elvish? Yeah, me too. I used to think cloud billing was just an annoying backend detail. "It scales, right? That’s the dream!" Until I realized we weren’t scaling—we were leaking money like a perforated S3 bucket. That’s when I met FinOps. Not a tool. Not a vendor. A mindset. A practice. A way to finally make sense of cloud costs without becoming a full-time accountant. Think DevOps, but for money. FinOps (short for Cloud Financial Operations) is how teams—especially devs, finance, and product folks—collaborate to: Understand where cloud money is going, Optimize usa…  ( 4 min )

One of the most valuable and underestimated tools in cybersecurity is the log parser. Every system, application, and network device generates logs, and hidden within these logs are the clues to attacks, misconfigurations, and system health issues. The challenge is not collecting logs, but making sense of them efficiently. That is where Python steps in as a powerful ally. In this article, we will walk through the principles of building a custom log parser using Python. Whether your logs come from web servers, firewalls, or authentication systems, being able to process and analyze them is essential for anyone interested in security operations, threat hunting, or incident response. To begin with, it is important to understand what logs really are. At their core, logs are just text files fille…  ( 6 min )

What Slows Mobile Teams Down When Launching Projects Mobile development in a traditional architecture remains complex and resource-intensive. Most teams face a heavy technical burden right from the start: building and maintaining backend infrastructure, handling DevOps tasks, configuring servers, integrating APIs, and ensuring stability and scalability.

Today was a solid day — tackled 4 more problems that deepened my understanding of hashing and stack-based logic. Covered some variety: hash frequency, prefix sum tricks, and even a stack-based temperature-wait problem. Here’s the breakdown: Problem: Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1 <= k < nums.length) such that the resulting array is nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ..., nums[k-1]. For example, [0,1,2,4,5,6,7] might be rotated at pivot index 3 and become [4,5,6,7,0,1,2]. Given the array nums after the possible rotation and an integer target, return the index of target if it is in nums, or -1 if it is not in nums. You must write an algorithm with O(log n) runtime complexity. Link to problem: https://leetco…  ( 4 min )

TL;DR: Higher-Order Functions (HOFs) are functions that receive or return other functions. They’re key to functional programming, widely used in React, map(), filter(), and more. They help abstract repetitive logic, making your code cleaner, testable, and elegant. Classic examples: setTimeout, Array.map(), Array.filter(), function factories. Higher-Order Functions (HOFs), or First-Class Functions, became a hot topic in JavaScript over the last few years — largely thanks to functional programming principles and React. But despite the intimidating name, HOFs are actually pretty simple. They can be defined as: Functions that takes one (or more) functions as parameters, or Functions that return another function But what’s the point of passing a function as a parameter?

Se você já trabalhou com APIs em .NET, provavelmente já ouviu falar sobre Middlewares. Mas afinal, o que são e por que são tão importantes? Neste artigo, vamos explorar o conceito de Middlewares no contexto de APIs .NET, entender como eles funcionam e ver exemplos práticos de como utilizá-los. O que são Middlewares? Middlewares são componentes que formam o pipeline de processamento de requisições em uma aplicação .NET. Eles são responsáveis por lidar com solicitações HTTP (requests) e respostas HTTP (responses), permitindo executar lógicas antes e depois que uma requisição chegue ao seu endpoint final. Pense em um middleware como uma "camada" que a requisição passa antes de chegar ao seu destino (e também na volta, quando a resposta é enviada ao cliente).

I completed General Assembly’s Web Developer Immersive in 2016. Back then, the curriculum focused on Vanilla JavaScript, jQuery, raw Ruby, Ruby on Rails, and the MEAN stack (MongoDB, Express, AngularJS, Node). At the time, everything moved at breakneck speed—and while we covered a lot, I don’t think the fundamentals ever had time to really sink in. What I did admire was the program’s emphasis on building and deploying projects. You were thrown into the deep end—forced to wrestle with unfamiliar concepts and figure things out as you built. Pre-LLM, that approach made sense. You just pushed through and got something working. Whether that led to long-term understanding, though, was a different story. It wasn’t until I enrolled in CSMC 203: Introduction to Programming at Montgomery College that things finally began to click. That foundational class helped me breeze through CSMC 206: Python Programming, and from there, everything felt more grounded. Eventually, I transferred to the University of Illinois Chicago to finish my CS degree. Being at a large public university, many professors rely on autograders to evaluate code. Imagine your first programming project being run through HackerRank or LeetCode-style tests without ever really being shown how to solve a problem. It’s easy to see how that could be discouraging—maybe even enough to push someone out of the field entirely. And UIC? They pile on the homework, especially in the engineering department. There isn’t much space to breathe, let alone learn deeply, until the semester ends. I’ve been balancing work and school for a while now, and I finally have the time and mental bandwidth to prove what I’m capable of—not as a cog in an assembly line, but as a developer who builds with intention. Over the coming months, I plan to build and share 12 projects that demonstrate why I’m a senior developer—and why I’m qualified for just about any role I apply to.  ( 3 min )

In computer systems, username and password has become a widely used way to authenticate users. The evolution of password storage and authentication methods has gone through various stages to enhance security and protect user credentials. Here's an overview of the progression from plain text passwords to using Secure Remote Password (SRP) and the key concepts at each stage: Plain Text Passwords: In the early days of computing and network authentication, passwords were often stored in plain text on servers. This means that when a user entered their password, it was stored exactly as entered. The main problem with plain text storage is that if the server is compromised, attackers can easily obtain the passwords, potentially leading to unauthorized access to user accounts.

For several years form-data.com offered a forms-backend as a service, for people building their own static forms. Creating a form builder was an idea that I played with for a long time. However, as a developer I didn’t like most of the form builders out there. It always feels like I have to fill-in a (really complicated) form just to create a form. What I ended up with was a text-to-form builder. On the left you write simple text descriptor, and on the right you get a form. And of course, as with any product these days, you can just ask the AI to write it for you. Publish the form is simple, and you’ve got yourself a hosted form. And the backend gets all you’d expect from a forms the backend, including spam filter, email notifications, auto-response emails and integrations.

The primary focus was the update of the base image from Perl 5.40.1 to Perl 5.40.2. I had recently updated my Docker tooling, but without noticing any changes until now. My editor VSCode suggested that I pinned the Docker image to a specific version , a technique I have used and am using with GitHub Actions. I thought this would be straight forward, but it turned out to be a bit more complicated than I expected. Not that it was compli…  ( 5 min )

Web applications come in many different forms and use various rendering patterns to display content to the user. These patterns dictate how the application is built, how it is served to users, and how it interacts with the browser. In this blog post, we will explore some of the most common rendering patterns used in web development, including static websites, single-page applications, server-side rendering (SSR), static site generation (SSG), incremental static regeneration (ISR), hydration, partial hydration, islands, streaming SSR, and resumability. Static websites are the most basic type of web application. They consist of HTML, CSS, and JavaScript files that are pre-rendered and served directly to the user's browser. This means that every page on the website is a separate file, and eac…  ( 6 min )

Starting my cloud computing journey with AWS Cloud Practitioner, I honestly struggled to grasp some of the concepts. Networking, IPs, even the general cloud terms, all felt new and overwhelming. Despite the struggles, I had already set a purpose: to understand why things work the way they do, not just memorize terms. So I started digging deeper apart from the AWS student guide, I watched YouTube explainers, reading more AWS docs, and learning from how experts on LinkedIn approach problems. One thing that helped a lot was reading how cloud professionals think about business needs of their clients, and how they approach AWS tools and services to solve them efficiently. Learning by Research & Reasoning CIDR and IP ranges Subnets and routing Internet Gateways and NAT Gateways I watched experts like NetworkChuck on youtube explaining how these connect in real cloud architectures, and attended a few expert sessions(like the ones from ALX) to build deeper understanding. I also documented everything on Notion, using toggles to organize concepts clearly and link them to real examples. Writing things out helped me make sense of abstract topics. Hands-On: Bringing It All Together After building that foundational understanding, I went hands-on with the AWS Console and practiced: Launching EC2 instances (choosing AMIs, instance types, configuring VPCs/subnets) Setting up IAM roles and using User Data scripts for automation Using key pairs and Git Bash to SSH into my instance Ran this command to verify the system: Got this output: 5.10.236-227.928.amzn2.x86_64 Amazon Linux 2 I explored basic Linux commands, storage configs, and how tagging and security groups improve structure and access. Progress Over Perfection I’m Curious… If you’ve walked the AWS learning path, what was your turning point? Was there a concept that “clicked” and made the rest easier? I Would love to hear how you approached your learning as a beginner or mentor. 👇  ( 4 min )

Google OAuth allows users to sign in to your site using their Google account, instead of creating a new username and having to remember yet another password. It also saves development time and greatly reduces security risks, because you wouldn't have to build registration forms and handle password hashing and storage. In this article, I'm going to show you how I implemented "Log in/Continue with Google" in my full-stack web application, and how you can too in your project. Before we proceed, it's worth noting that this article was written with a specific stack in mind. There will be slight differences in implementation details depending on what stack your application uses. If this is a feature you want your application to have, and you happen to be using a different stack, you can still re…  ( 8 min )

TL;DR If you finished the Intro to ML post and thought, “Cool, but real data is way uglier,” this follow‑up is for you. We’ll use the same California Housing dataset so you can reuse your environment and immediately see the effects of each technique. When sensors drop packets or humans skip survey fields, you get NaN (Not‑a‑Number) entries. Most scikit‑learn models will straight‑up error if you feed them NaNs, so we MUST decide what to do. The three classic moves are: Strategy What it does When it’s OK Drop Columns Delete any column containing any NaNs Column is mostly NaNs or not predictive Imputation Replace NaNs with a statistic (mean/median) Numeric columns with moderate sparsity Extended Imputation Impute and add a boolean “was_missing” flag When the fact a value is missin…  ( 6 min )

The real problem with Web Components is simple: There is no clearly defined road to success for using them. No singular go-to guide. Up until recently the standard has been in flux. And in some ways, still is. But the core APIs have stabilized, and many developers are jumping into the scene. However, it can be hard for someone who hasn't followed the evolution of this standard to know where to begin. Learning the concepts necessary to use this powerful set of tools is a challenge. Many articles exist on this subject, but the real useful information is scattered, buried among outdated tutorials demonstrating experimental features that have changed over the years. So, if you have been wondering how to get to started crafting your own components from scratch, you are reading the right article…  ( 8 min )

AI-powered code suggestions from tools like Cursor and Windsurf can introduce security flaws for several reasons. First, these models are built on extensive datasets that include publicly available code and third-party libraries, many of which already contain known weaknesses. As a result, the AI may inadvertently learn and replicate those insecure patterns. Additionally, these tools often produce predictable and repetitive code structures that, while syntactically correct, may be vulnerable to exploitation if not verified properly. Another key concern is their limited understanding of the broader application environment, including specific business logic or security policies, leading to code suggestions that may function correctly but pose risks when deployed. The fast-paced nature of A…  ( 4 min )

The Blog Post Release Automation I made this mistake this week of believing I wanted to automate, using an LLM of course, some parts of the painful podcast release cycle. Weekly I record episodes of the podcast Adventures in DevOps with my awesome co-host. Of course all the episodes are available on our podcast website as well other streaming platforms. But! Since we're a technical podcast, we decided to make our infrastructure open source (On GitHub unfortunately), but to go further it also uses GitHub Actions to publish the episodes to our website. There is of course the nasty bit of actually recording the episodes, editing the episodes, and then downloading and formatting them to make them nice.

Introduction If you’re a JavaScript developer diving into Python, you’ll find many concepts familiar but with syntactic twists. Python’s emphasis on readability and simplicity means fewer brackets, strict indentation, and a different approach to common tasks. Let’s break down key differences with side-by-side examples. 1. Variables and Constants JavaScript let mutableVar = 10; // Mutable const immutableVar = 20; // Immutable Python mutable_var = 10 # No 'let' or 'const'—all variables are mutable IMMUTABLE_VAR = 20 # Convention: UPPER_CASE for "constants" (not enforced) Key Notes: Python uses snake_case (not camelCase).

If you’ve worked with Laravel, you’ve typed php artisan serve php artisan migrate. And while those are useful, they barely scratch the surface of what Artisan can do. Artisan isn’t just a tool for running migrations or spinning up servers—it’s a command-line companion that can boost your productivity, simplify debugging, and teach you more about Laravel’s inner workings. Yet many developers (my past self included) tend to stick with the same 3-4 commands and miss out on some seriously powerful features. Whether you’re just starting with Laravel or you’ve been building apps for years, it’s worth revisiting Artisan with fresh eyes. In this post, I’m diving into some of the lesser-known, underrated, or just plain useful Artisan commands I think every Laravel developer should explore. php art…  ( 5 min )

A class in JavaScript is a blueprint for creating objects. It allows you to define reusable object structures with properties and methods, making object creation and management more structured and efficient. JavaScript classes are a blueprint for creating objects. They introduce object-oriented programming (OOP) concepts like encapsulation, inheritance, and abstraction. Before ES6, JavaScript used constructor functions and prototypes to create and manage objects. With ES6, class syntax was introduced to provide a cleaner, more intuitive way to define object templates. JavaScript allows creating objects without classes using object literals, but classes provide advantages in scalability, maintainability, and reusability. Let's explore: class Person { constructor(name, age) { this.name…  ( 11 min )

Hello friends 👋 In this blog, I will explain two simple and powerful tools in JavaScript: the AND (&&) and OR (||) operators. These are called logical operators and are used to check conditions. Let’s understand them with examples that relate to real life 🚶‍♂️🍕💻 AND (&&)? The && operator checks if both conditions are true ✅✅ If both are true → result is true If any one is false → result is false ❌ Let’s say you want to go for a walk 🚶‍♀️ You will go only if: ➡️ It is not raining ☀️ AND ➡️ You have free time 🕒 let isNotRaining = true; let hasFreeTime = true; if (isNotRaining && hasFreeTime) { console.log("You can go for a walk! 🚶‍♂️"); } else { console.log("Stay at home! 🏡"); } 📌 If both conditions are true, the walk will happen 📌 If even one is false, no walk today! OR (||)? The || operator checks if at least one condition is true ✅ If one is true → result is true If both are false → result is false ❌❌ You will order food 🍔 if: ➡️ You are hungry 😋 OR ➡️ There is no food at home 🍳 let isHungry = false; let noFoodAtHome = true; if (isHungry || noFoodAtHome) { console.log("Order food online! 🛵"); } else { console.log("No need to order food. Eat at home! 🍽️"); } 📌 Only one condition needs to be true to order food ➡️ && → Both conditions must be true ✅ AND ✅ ➡️ || → Only one condition needs to be true ✅ OR ❌ let hasLaptop = true; let hasInternet = false; // Check if you can work from home if (hasLaptop && hasInternet) { console.log("You can work from home 💻🏠"); } else { console.log("You can't work from home 😕"); } // Check if you can still do something useful if (hasLaptop || hasInternet) { console.log("You can still be productive! 💡"); } Operator Result is true if... AND Both conditions are true ✅✅ OR At least one condition is true ✅ or ✅ I hope this blog helps you understand AND and OR operators in a fun and easy way! 😊 These are very helpful when writing conditions in JavaScript.

This post dives into Plang, an intent-based programming language that interprets natural language. For more, visit plang.is or get started here. Security is hard. As developers, we’re not exactly great at it. The issue is that security is binary - it either works 100% or it doesn’t at all. If there’s a flaw in your code, an attacker could gain full access to your system. Worse, you can never truly prove that something is 100% secure. All you can do is try to prevent every possible way in, which requires a lot of experience and a lot of eyes on the code. The only thing that gets you closer to 100% is time and scrutiny. That’s the key to secure code: experienced developers looking at it, lots of them, and enough time passing without a breach. We never know it’s secure. We can only hope. If I…  ( 5 min )

Hi, I'm Choice 👋🏽 I’m a Ruby on Rails developer with a background in chemistry — but really, I’m someone who’s rebuilding life from the inside out. My journey into tech wasn't linear. Like many Nigerians, I studied something safe (Chemistry), even though I’d always loved computers. Life happened, and I took detours that forced me to pause, reflect, and reimagine everything. Coding became more than a skill; it became a language of healing, structure, and hope. Since transitioning, I’ve built full-stack apps like ShopMe (e-commerce), DevConnect (developer community), and I’m currently working on TextMe, a real-time chat app. I’ve used tools like: Ruby on Rails (8), SolidQueue for background jobs AWS S3 for image storage React, Firebase, TailwindCSS, Bootstrap I’m also learning Django and Next.js 🌱 But beyond the tech, I’m creating soulful, user-centered projects — the kind that feel like quiet spaces on the internet. My content brand DearChoice is where I share faith, healing, and growth. My passion project Yardly aims to help communities in Nigeria discover local talents and preserve culture — online. I want to connect with devs who are learning with heart. Who are figuring things out slowly. Who care about the why, not just the how. If that sounds like you, let’s chat 🤝 Let’s build, share, reflect — and grow better together. ✨ 🧩 You can check out my projects on GitHub @ChoiceG 💼 And find me on LinkedIn See you around! – Choice 🌿  ( 3 min )

If you've ever pushed a hotfix on Friday, only to get a bug report five minutes later… You know the pain of mobile testing. Between flaky UI tests, emulator delays, and device-specific weirdness, testing often feels like guesswork. We wanted something cleaner and found that API-driven mobile testing changes the game. Emulators that crash at the worst times Tests that pass locally but fail in CI Writing brittle UI test scripts that break on every UI tweak Hours wasted waiting for device builds to finish Sound familiar? We figured there had to be a better way - and there is. Instead of relying solely on UI flows, we started triggering mobile app behavior via APIs during CI runs. This gave us: More control over test execution The ability to skip the UI when not needed True automation across devices, even without a UI Turns out, you don’t need to “see” the app to know it’s working - you just need to test the right paths, fast. We integrated a lightweight API testing layer into our existing pipeline. We used a tool that let us: Run tests on real devices, remotely Trigger workflows from GitHub Actions Receive results via webhook Skip maintaining emulator scripts It plugged into our pipeline almost effortlessly, and we never looked back. Less flakiness Faster feedback Works across device types Easy to scale Most importantly, it lets us move fast without breaking things. We tried a few things, but ended up using tools like NativeBridge(the cheapest), Appetize, BrowserStack, and Lambda that made the API integration part smooth. No SDK installs, no heavy setup — just clean test runs triggered by API. We didn’t plan to switch our whole testing strategy, but it kind of happened naturally once we saw how stable and scalable it felt. You don’t need to rewrite your entire testing suite. Just look for places where API-driven checks can replace manual ones — and start small. It’s not about being trendy — it’s about not burning out your dev team maintaining flaky test code.  ( 4 min )

Today, I learned about CSS Transforms, and I’m excited to share what I discovered! The transform property in CSS lets you visually manipulate elements — you can move, rotate, scale, and skew them without changing the actual layout. It's super useful for animations, hover effects, and modern UI design. Here are some common 2D transform functions: translate(x, y) Moves an element from its original position. transform: translate(50px, 100px); rotate(angle) Rotates an element clockwise. transform: rotate(45deg); scale(x, y) Scales an element in the X and Y directions. transform: scale(1.5, 1.5); skew(x-angle, y-angle) Skews the element. transform: skew(20deg, 10deg); 3D transforms add depth to your elements and make them appear to move in 3D space. To view them properly, you often need to use the perspective property on the parent container. rotateX(angle) Rotates the element around the X-axis. transform: rotateX(45deg); rotateY(angle) Rotates the element around the Y-axis. transform: rotateY(45deg); rotateZ(angle) Rotates the element around the Z-axis (similar to 2D rotate). transform: rotateZ(45deg); translateZ(distance) Moves the element closer or farther away in 3D space. transform: translateZ(50px); perspective(n) Defines the distance between the viewer and the 3D element. .parent { perspective: 500px; } .box { width: 100px; height: 100px; background: teal; transition: transform 0.3s; } .box:hover { transform: scale(1.2) rotate(10deg); } When you hover over the box, it grows and rotates — all thanks to the transform property! CSS transforms (2D and 3D) are powerful tools that add creativity and interaction to your web designs. I enjoyed experimenting with different effects and seeing how elements can move and rotate on screen. Next, I’m planning to learn about CSS animations and how they work with transforms.  ( 4 min )

Hello everyone 👋 I’ve recently started building a personal open source project called Cartouche. It’s a one-user social network simulator. You write posts like on Twitter, and get reactions from hundreds (or thousands) of AI bots — each with memory, personality, and their own behavior. The idea Cartouche is a place to express yourself freely — without the pressure of real audiences. You get thoughtful replies, memes, debates, praise, skepticism, and support… but all of it from simulated users with their own quirks and styles. They react over time, not instantly. Some follow you, others unfollow. Some remember what you said weeks ago. Some adore you. Some argue. Some just drop a meme and vanish. It’s a space for testing ideas, exploring identity, or just yelling into a virtual crowd that somehow yells back — in meaningful, sometimes surprising ways. Why? Because sometimes you want feedback — but not from real people. What's built so far? A small piece of the frontend (React + Vite) A mobile-first UI (with live demo): View Demo Figma design (mobile): View on Figma GitHub repo: Cartouche on GitHub Full project overview (Gist): Read here Tech stack (planned) Frontend: React + Vite (hosted via Nginx in Docker) Backend: Python (likely FastAPI) Storage: MinIO for media Database: MySQL, maybe Redis AI: Google Gemini API (or user’s choice) Deployment: All via Docker Compose, one-command setup Looking for like-minded folks I’m building this solo for now. It’s a pet project — no deadlines, no pressure, no money involved. Just a place to build something interesting and fun. If this concept resonates with you and you'd like to contribute — whether with code, ideas, or questions — feel free to reach out. Happy to chat. Thanks for reading. — @metimol  ( 3 min )

Have you ever thought about how the simple act of weaving cloth is connected to the computers we use today? It might sound surprising, but the story of computers begins with weaving looms! Long ago, people used looms to weave fabric. These looms created patterns by controlling how threads crossed each other. In the early 1800s, a clever inventor named Joseph-Marie Jacquard invented a loom that used punched cards to tell the machine which pattern to weave. These cards acted like instructions — telling the loom what to do step by step. This was one of the first examples of a programmable machine — a machine that could follow a set of instructions automatically. Around the same time, inventors were building machines to help with calculations. People like Blaise Pascal and Gottfried Wilhelm Le…  ( 4 min )

We are continuing the blog series about testing your AWS alarms. The first part of the series, which looked at CloudWatch actions and EC2 alarms, can be found here. An untested alarm is not one you can trust. This time we will look at alarms for your Lambda functions. As before, we will test the alarms by ”breaking” the Lambda so you get the same outcome as when a real issue would occur. Since this is Lambda, we will add code (or entire Lambdas) to make the Lambda act as we want. I will use Python, but the logic works for all the other supported languages. I have an examples repo where you can find Terraform code to deploy Lambas and required resources to AWS to test the alarms. You will need to connect your alarms to the Lambda functions, though. Remember to lower the thresholds on your a…  ( 6 min )

A growing problem with my home lab is password fatigue. Each time I add a new service to my network, I generate a new random password for it. I got by initially with using a different password for every service by storing them in a password manager, but as the number of services exceeded double digits, having to open my password manager every time I want to access each service is starting to hinder my productivity. I needed a self-hosted SSO solution for my home lab services, so I deployed an open-source IAM platform that supports SSO via OIDC, OAuth, and LDAP protocols to my Kubernetes cluster. The initial design was simple. I only needed SSO for my services, namely Grafana and Syncthing, and my solution must support both modern protocols like OAuth/OIDC and legacy protocols like LDAP.

Originally published at https://www.nocobase.com/en/blog/open-source-ticketing-systems. Last year, as the number of NocoBase users grew, we faced a pressing challenge: how to efficiently manage customer feedback and support requests. Users reached out via emails, community forums, and even through internal colleagues. With information scattered across multiple channels, issues were easily missed, and collaboration on follow-ups became cumbersome. We realized it was time to implement a ticketing system tailored to our workflows. So, we decided to build our own custom ticketing system using NocoBase. During this process, we tested several open-source projects and identified some excellent tools, while also defining the core features essential for an effective ticketing system.

Schemas in PostgreSQL aren’t just for large systems—they’re for anyone who wants to keep their data structured. A schema is like a folder within your database where related objects (tables, views, etc.) are grouped together. This helps you separate concerns, organize logic, and secure your data more effectively. Here’s a practical look at how they work. Organization: Separate business domains (like inventory and users). Control: Limit access to different parts of your app. Maintenance: Make backups and updates more targeted. Cleaner Queries: Avoid clutter in your namespace. Comes with every PostgreSQL database. If you don’t specify a schema, objects go here. Created manually to isolate logic or control access. CREATE SCHEMA hr; How Data is Structured PostgreSQL Cluster └── Database └── Schema └── Tables, Views, Functions, etc. This layered model helps manage growing projects without chaos. CREATE SCHEMA inventory; CREATE TABLE inventory.products ( product_id serial PRIMARY KEY, product_name VARCHAR(255), price DECIMAL, stock_quantity INT ); CREATE TABLE public.users ( user_id serial PRIMARY KEY, username TEXT, email TEXT ); Using schemas lets you organize your app by responsibility—making it easier to evolve or scale parts of your system. Yes, and it’s a common best practice. Public is open by default; custom is restricted unless granted. Not directly, but they help manage large systems more cleanly. Yes, using tools like pg_dump or schema migration scripts. PostgreSQL schemas give you better structure, access control, and scalability. They're an essential tool for organizing your data without complicating your architecture. For a more detailed guide, visit the schemas in PostgreSQL article.  ( 17 min )

Docker has revolutionized the way developers build, ship, and run applications. Whether you're a beginner or an experienced developer, mastering these essential Docker commands and tips will make you more efficient and productive. Before using Docker, ensure you have it installed by running: docker --version To get detailed system info, use: docker info Quickly run a container with: docker run -d -p 8080:80 --name my-container nginx This runs an Nginx server in detached mode (-d), mapping port 8080 on your machine to port 80 inside the container. To see all running containers: docker ps To include stopped containers: docker ps -a Stop a running container: docker stop my-container Remove a stopped container: docker rm my-container Remove all stopped containers at once: docker rm $(docker ps -aq) Over time, unused images take up space. Remove them with: docker image prune -a If you have a Dockerfile, build an image with: docker build -t my-app . This tags the image as my-app. Use interactive mode to execute commands inside a running container: docker exec -it my-container /bin/sh For Ubuntu-based containers, use /bin/bash. Monitor logs with: docker logs -f my-container The -f flag shows real-time updates. Copy files from your local machine to a running container: docker cp myfile.txt my-container:/app/ Copy files from a container to your machine: docker cp my-container:/app/myfile.txt . Instead of running multiple containers manually, define them in docker-compose.yml and start them with: docker-compose up -d Stop and remove all services: docker-compose down 💼 LinkedIn | 📂 GitHub | ✍️ Dev.to | 🌐 Hashnode Found this useful?

When working with query parameters in your React app, especially in tools like filters, pagination, or search inputs, you often want to persist those query parameters as users navigate across different views. In this post, you'll learn how to build a simple and reusable custom React hook using react-router-dom that preserves query parameters during route changes. Imagine you're on a URL like: /products?category=books&page=2 Now you click on a product to go to its detail page: navigate('/products/123') 💥 Boom! You lose your query params. When the user clicks the back button, they're dropped on /products instead of where they left off (/products?category=books&page=2). Let’s fix that by creating a useNavigateWithQuery hook.

This feels so fluid… how do they do that?’" If you're a frontend developer in 2025, chances are you’ve asked yourself this at least once. Animations have quietly become one of the most influential parts of the user experience. They’re no longer just about making things "look cool"—they guide the user, provide feedback, and elevate interaction into engagement. In the early 2010s, animations were mostly afterthoughts—extra polish added at the end of a project if there was time. Today, they are baked into the design process from Day 1. With products competing for attention in milliseconds, smooth transitions, responsive feedback, and motion-based storytelling are the new UX fundamentals. But here's the catch—not a…  ( 8 min )

tldr; I passed! It took me 2 weeks to study, and I’m sharing my thoughts. Allot 1–2 hours of study time every day leading up to the exam, and take practice exams to gauge your understanding and reinforce weak areas. I've written in my previous post that I had to scratch the itch and dive back into AWS. Since then, I’ve studied and passed the certification. Now I can brag on my LinkedIn profile about my shiny new certificate. Of course, I also immediately added it to my resume website! Actually, no. To be honest, it’s always still best to have real-world experience over a certificate.

Ever stared at a loading bar, wondering if you have time to grab coffee before it finishes? Here's a solution I built for that universal pain point. Try it now: Upload Time Estimator Last month, I was uploading a 2GB video project over a flaky connection. The browser gave me zero insight—just a spinning wheel of doom. "How long is this going to take?" I wondered. "Should I cancel and try later? Will it finish before my meeting?" That frustration sparked an idea. What if I built a tool that could predict upload times before users commit to them? We often overlook upload experiences in our applications. But for users, especially those with slower connections, this can be a major pain point.

How an AI Interview Coach Helped Me Land My Dream Dev Job Let me start with this: I’ve always dreaded technical interviews. The whiteboard questions, the algorithm drills, the awkward silences when you blank out mid-sentence... it’s brutal.

Type Inference TypeScript can often guess types automatically. This is called type inference. When you assign a value without an explicit type, TypeScript infers it. For example: let count = 10; // inferred as number let message = "Hello"; // inferred as string The compiler knows count is a number and message is a string from these initial values. Type inference helps keep code concise and still type-safe. You don't always need to write : number or : string because TypeScript figures it out. Less code: You skip repetitive type annotations. Safety: Even with fewer annotations, TypeScript checks types. Readability: Code stays clean while avoiding obvious errors. However, you can still add type annotations if it makes the code clearer or if a variable’s type isn’t obvious. …  ( 6 min )

The US Department of Justice is reportedly conducting a probe over Coinbase’s contracted customer service agents in India, who accepted bribes in exchange for allowing criminals access to user data. According to a May 19 Bloomberg report, DOJ investigators are looking into the data breach, which Coinbase disclosed to the public on May 15. The exchange reported that a group of customer support contractors — subsequently fired — “abused their access to [...] systems to steal the account data for a small subset of customers.” “We have notified and are working with the DOJ and other US and international law enforcement agencies and welcome law enforcement’s pursuit of criminal charges against these bad actors,” said Coinbase’s chief legal officer, Paul Grewal, according to Bloomberg. Related: New Zealand man arrested in $265M crypto scam tied to FBI probe Though “no passwords, private keys, or funds were exposed” according to Coinbase, the data breach resulted in social engineering attacks targeting users, including a Sequoia Capital partner, with losses estimated at up to $400 million. The attackers also attempted to extort $20 million from Coinbase in exchange for not disclosing the breach, which the company refused. Backlash in the courts The attempted social engineering attacks have resulted in Coinbase users filing several lawsuits against the exchange, alleging that the company mishandled their personal data. One user, a retired artist named Ed Suman, reported losing $2 million to the scammers. Coinbase’s stock price fluctuated following the news of the breach and an unrelated probe from the US Securities and Exchange Commission over its reported “verified user” numbers. Cointelegraph reached out to Coinbase for comment but had not received a response at the time of publication. Magazine: Father-son team lists Africa’s XRP Healthcare on Canadian stock exchange

On May 22, US President Donald Trump is expected to host up to 220 people who had purchased the most significant quantities of his memecoin at a private event in Washington, DC. Though the exact number of attendees was unknown as of May 19, reports and blockchain data have revealed some of the tokenholders who qualified to apply for the May 22 dinner and “VIP tour” and reception, presumed to be in the White House. Bloomberg reported on May 7 that more than half of the 220 wallets were likely controlled by foreign nationals.

Circle, the issuer of stablecoin USDC (USDC), is still planning an initial public offering (IPO), but the company is also in informal talks with Ripple and Coinbase about a sale, according to a report from Fortune.

Ripple tried to purchase Circle on April 30, but the $4 billion to $5 billion bid was rejected as being too low. If Ripple or Coinbase were to buy Circle, the details of a purchase would differ.

Coinbase and Circle have a relationship dating to 2018, when they launched the Centre Consortium. That ventur…

Key takeaways: Bitcoin buying in the spot and futures markets helped BTC price keep its upward momentum despite $170 million in margin liquidations. Weak stablecoin demand in China and the limited use of futures leverage suggest Bitcoin’s current rally is sustainable.

The abrupt $5,000 correction after hitting $107,090 may have been unexpected, but it does not mean the odds of reaching an all-time high in the near term are lower, especially since Bitcoin derivatives metrics have shown resilience.

Before discovering Bitcoin (BTC), Ledn co-founder Mauricio di Bartolomeo found success shorting the Venezuelan Bolivar as it rapidly lost value against the stronger US dollar. Now, with the US dollar depreciating against Bitcoin, borrowing against Bitcoin instead of selling it has become a more viable strategy. “Prior to Bitcoin, my most successful investment was shorting the Bolivar with dollars,” di Bartolomeo told Cointelegraph in an exclusive interview at the Consensus conference in Toronto, Canada.  “I was borrowing Bolivars and buying dollars with them, holding the hard dollars and having a borrow [position] on the weaker currency,” he said. The arrival of Bitcoin-backed loans means investors can now effectively implement the same strategy by using a harder currency as collateral.  L…

Key takeaways: Bitcoin recovered from its sharp sell-off from $107,000, suggesting it functions as a hedge against uncertainty for investors reacting to Moody’s recent downgrade of US debt. Moody’s downgraded the US credit rating to Aa1, citing a $36 trillion debt and rising deficits, causing market turbulence and a spike in US Treasury yields. Despite short-term pressure from macroeconomic shifts, Bitcoin’s long-term outlook remains bullish due to cautious shorting and a weakening US dollar.

Opinion by: Darius Moukhtarzadeh, Research Strategist at 21Shares A new wave of crypto fundraising is emerging, changing how Web3 projects launch and who can invest at an early stage: Community Sales. At first glance, community sales may seem reminiscent of the ICO (Initial Coin Offering) era from 2016–2017. Yet, they represent a significant evolution that better aligns with crypto's core values of democratization, transparency, and inclusivity. Projects should include community sales as a core element of their fundraising strategy, besides raising from angel investors and VCs. Professional investors should embrace community sales as they highly increase the chances of sustainable success of Web3 projects.  The ICO era The original ICO boom promised broad retail participation and democrati…

Franklin, a hybrid cash and crypto payroll provider, is launching a new initiative that aims to turn idle-sitting payroll into an opportunity for yield. The new solution, dubbed Payroll Treasury Yield, uses blockchain lending protocols to help firms earn returns on payroll funds that would otherwise sit idle, the company told Cointelegraph in an exclusive statement.

These funds are lent to vetted borrowers, and companies earn yields while retaining access to their capital. Companies maintain full custody throughout the process, and smart contracts used are audited to reduce risk. …

A court decision in Australia could open the door to as much as $640 million in capital gains tax (CGT) refunds on Bitcoin transactions after a judge ruled that crypto should be treated as money rather than a taxable asset.  On May 19, the Australian Financial Review (AFR) reported that the decision arose within a criminal case involving federal police officer William Wheatley, who allegedly stole 81.6 Bitcoin (BTC) in 2019.

In the case, Judge Michael O’Connell of Victoria ruled that Bitcoin qualifies as a form of money rather than property, likening the digital asset to Australian dollars rather than to shares, gold or foreign currency. The interpretation could se…

What is a crypto drainer? A crypto drainer is a malicious script designed to steal cryptocurrency from your wallet. Unlike regular phishing attacks that try to capture login credentials, a crypto drainer tricks you into connecting your wallets, such as MetaMask or Phantom, and unknowingly authorizing transactions that grant them access to your funds.

Ethereum co-founder Vitalik Buterin unveiled a proposal to preserve trustless, censorship-resistant access to Ethereum, even as the network scales.  On May 19, Buterin shared a post outlining how to make Ethereum’s layer-1 scaling “more friendly” to users running local nodes for personal use. The Ethereum co-founder highlighted the importance of independent users running nodes, saying that a market dominated by a few Remote Procedure Call (RPC) providers risks censorship.  RPC providers let wallets, users and apps interact with the blockchain without running their own nodes. Crypto wallets are usually connected to an RPC provider behind the scenes. Buterin said there are risks to this setup.  “A market structure dominated by a few RPC providers is one that will face strong pressure to depl…

A recent proposal that aims to change Bitcoin’s base unit to make it easier to understand as a payment tool has run into opposition, with critics saying Bitcoin’s satoshis are no more confusing than the dollar’s cents. Bitcoin developer John Carvalho introduced Bitcoin Improvement Proposal-177 on April 23, which seeks to eliminate the concept of satoshis, of which there are 100,000,000 in 1 Bitcoin (BTC), and effectively split Bitcoin’s fixed supply of 21 million into 21 quadrillion units. It follows a 2017 proposal from Bitcoin developer Jimmy Song to create “bits,” representing one-millionth of 1 Bitcoin. However, Carvalho said Song’s approach would still require Bitcoin users to think about decimals and “shifts complexity rather than eliminating it.” Block Inc. CEO Jack Dorsey is among…

EPS vs PNG: What’s the Difference? EPS (Encapsulated PostScript) is a vector file format used mainly for print workflows and high-quality graphics. It retains shape, curve, and scaling data—great for logos and illustrations. PNG (Portable Network Graphics) is a raster format ideal for digital content. It supports transparency and lossless compression, making it perfect for websites, apps, and UIs. So why convert? Because: Browsers don’t support EPS natively PNG is lighter and easier to preview You might need thumbnails or web-friendly versions of design assets Python makes this easy using the wand library (a wrapper for ImageMagick): bash with Image(filename='logo.eps', resolution=300) as img: ImageMagick is a powerful command-line tool that supports EPS to PNG conversion out of the box: bash bash If you're building a web app or serverless function and don’t want to install heavy dependencies, consider these APIs: Cloudinary: Offers format transformation pipelines CloudConvert: Easy-to-use REST API ConvertAPI: Handles over 200 file types including EPS Here’s a sample request using CloudConvert: bash https://api.cloudconvert.com/v2/jobs \ Web apps that allow users to upload and preview logos or designs Automated pipelines for asset generation or optimization CMS tools that generate thumbnails or social previews from design files Whether you're writing a backend service or automating a design workflow, converting EPS to PNG is a straightforward but essential task. For local scripts, go with Python or ImageMagick. For cloud scalability, plug into an API. Got a preferred method or tip for EPS to PNG? Drop it in the comments or share it on GitHub.  ( 4 min )

Automation promises simplicity—tasks repeated flawlessly, outcomes consistently predictable, and infrastructure harmoniously stable. At the heart of these captivating promises lies idempotency , an elegant idea proclaiming that no matter how many times we run an operation, the result remains steadfastly unchanged. Yet, the shimmering promise of automation's reliability seldom matches reality. In the messy arenas of operational infrastructure, idempotency frequently escapes our grasp. Like a distant horizon, it coaxes and compels—but rarely feels fully attained. Why does the concept of reliable idempotency struggle when translated from whiteboards to production realities? The culprit is the capricious, ever-changing landscape of real-world infrastructure management. Consider a familiar scen…  ( 6 min )

"I didn’t know how anything would work when I started—just had a vague sense I’d figure it out along the way." I wanted to understand how computers really work—beyond just writing high-level code. I needed to deepen my knowledge and prove to myself that these low-level systems aren’t inherently difficult; you just need the right concepts. So, I decided to build a MIPS emulator. I broke it down into three parts: Loading the binary code from a MIPS program Decoding the binary instructions Executing them At first, I didn’t even know how to load a file, let alone parse instructions. So that’s where I began. We need a binary file that contains MIPS instructions in raw binary format. There are other formats like ELF, but I chose to keep it simple with a .bin file.

Introduction: The BPM Paradox Business Process Management (BPM) is designed to improve efficiency, streamline operations, and boost performance. In theory, it helps automate workflows, align teams, and bring structure to everyday tasks. But in reality, many companies are still using outdated, rigid, and overly complex BPM systems. They believe they’re becoming more efficient… when in fact, they’re silently slowing themselves down. What if your BPM system—designed to drive performance—is actually blocking innovation and costing you time? Business Process Management (BPM) is a discipline focused on modeling, analyzing, automating, and continuously improving business processes. It involves defining every step in a process (e.g., invoice approvals, onboarding, leave requests), and turning th…  ( 5 min )

Back then, there was just digital marketing. Then product marketing. We’d segment audiences, figure out what they need, fear, and want. We’d find where our product fits, then build campaigns to fish. Developer marketing isn’t so different. Except, once you identify this audience, you don’t fish. You sit with them. You learn their pain points. You plug into their workflow. You speak their language. And you earn the one thing that moves the needle: trust. I’ve written a lot about developer marketing. Most of it lives on The New Stack and Hackmamba.

Recentemente eu desenvolvi o desafio da Woovi com Koa.js e GraphQL (link do projeto).

No entanto, me deparei com alguns problemas iniciais: diversas funcionalidades não estavam presentes no graphql-http, visto que ele é apenas uma implementação do GraphQL sobre HTTP, isto é, é simples e minimalista. Primeiro, por quê? Bom, principalmente, porque koa-graphql foi praticamente descontinuado e graphql-http deve ser utilizado ao invés disso. Tomei esta decisão baseada em uma discussão que inclusive recomendava o uso do yoga, uma alternativa mais completa para servidores graphql, no entanto, eu vi que seria completamente capaz de resolver apenas com graphql-htt…  ( 5 min )

I completed the Hashmap project I realised that I hadn’t used node.js to do the Linked List project (and I should have), so for this project, I did not use an index.html and ran my file using node.js from within Visual Studio Code. In order to do this, I had to use VSC debugger and I had to admit that I found it tricky at first. Sometimes nothing happened when I stepped through the code, sometimes nothing got displayed to the console, but I persisted with it and managed to figure out enough to be able to debug and create a working program.

We often treat threat modeling and test planning as two separate disciplines. One belongs to the security team and lives in architecture diagrams. The other belongs to QA and rides shotgun with feature delivery. But in a world where security flaws are more business-critical than ever, this division doesn’t make much sense anymore. What if we stopped treating threat modeling as a theoretical security ritual and started using it as a blueprint for our test plans? What if the same mindset that helps identify potential attack vectors could also guide what we validate, automate, and protect in our test suites? Turns out, it can. Let’s be honest—most development workflows treat security as a checkpoint, not a mindset. You’ll hear “we’ve completed the threat model” during early planning. But week…  ( 5 min )

Hey Dev.to I’ve been building SkillTrack AI, a small open-source project that helps developers track their skills and growth powered by AI.

Timezones are more than just a technical nuisance — they're a real threat to global businesses. Missed meetings, broken calendar exports, and daylight saving errors can cost you clients, trust, and time. In this post, I’ll show you how I built a timezone conversion tool in Laravel that makes handling multiple timezones easy — even when your users span from Tokyo to Toronto. Let’s dive in. Imagine this: A user in Tokyo schedules a meeting at 2 PM local time. But someone in New York shows up at 1 AM because the app didn’t convert it right. 💀 Or worse: Calendar exports show incorrect times Daylight Saving Time changes break everything twice a year Manual conversions lead to bugs, missed events, and angry customers Sound familiar? You're not alone. That’s why I built a simple but powerful La…  ( 4 min )

Originally published on Medium. Motivation is great — when it shows up. But consistency builds skills, habits, and portfolios. Some days I wake up inspired to build something new. Other days, I don't even want to open my code editor. If I waited for motivation to show up, I'd still be stuck at day one. Motivation is emotional. It depends on sleep, mood, weather, food, dopamine, whatever. It’s not stable. And that’s fine — we’re human. But if we rely on it to work, we’ll work very little. I’ve lost count of how many times I told myself: “I’ll do it tomorrow when I feel more ready.” That tomorrow rarely came. Consistency doesn’t rely on feelings. It’s a system. A rhythm. A muscle. One commit a day One blog post a day One small bug fix Even when it’s not perfect, or exciting, or ideal — it adds up. I stopped overthinking I built projects faster I became more confident I got better — not in a dramatic way, but quietly, steadily Even this blog you’re reading — it exists because I chose to write daily, not when I “felt inspired.” “Write for 15 minutes.” “Fix one component.” Something so small, it feels easy to do — and hard to skip. I don’t care if today’s task is small or ugly. I care that I showed up and made a move. When it comes, I enjoy it. When it’s gone, I work anyway. Motivation is a great bonus. But consistency is what builds portfolios, opens doors, and turns beginners into professionals. Don’t wait for the right moment. Build the rhythm that brings progress — no matter how you feel. Do you rely on motivation, or do you have a system that keeps you moving? Let’s compare notes in the comments. ✍️ Written by @denizgokbudak Frontend developer sharing thoughts on discipline, AI, and real-world dev workflows.  ( 4 min )

what happens when the biggest liability becomes your greatest asset Introduction: Every dev team has that one engineer. You know the one. The code commit comes in and suddenly half of staging is on fire. They push on main, forget semicolons, and somehow manage to brick a Docker container by renaming a folder. At first, we laughed. Then we cried. Then we made rules like “Nobody touches deploy unless it’s Monday–Wednesday, 9 to 5, and you’ve had coffee.” This person, let’s call him Dave, wasn’t just junior. Dave was entropy in human form. If there was a weak spot in the system, Dave would find it not on purpose, just as a side effect of existing. We called him the worst programmer on the team. But we were wrong. Because Dave didn’t just write questionable code he revealed where our system w…  ( 9 min )

from meetings that could’ve been Slack messages to debugging nightmares at 3AM this is what dev life really looks like. Introduction If you’re a software engineer and feel like you’re slowly losing your grip on reality, congratulations you’re not broken. You’re just in tech. The job description promised creativity, deep focus, and the thrill of building great products. Instead, you wake up to 89 Slack notifications, a failing CI pipeline, and a calendar stuffed with meetings labeled “Quick Sync” that last 45 minutes and accomplish nothing. Somewhere between pushing code, deciphering broken dependencies, and watching product managers say “just a small tweak,” you realize this isn’t exactly what you signed up for. And yet… here you are.

Still on the subject of post macOS clean reinstall tips, if control + space stops doing what it is supposed to do — such as autocompletion suggestions on Visual Studio Code —, it is probably caused by macOS global shortcut.

Hey there, fellow developer! 👋 Let's talk about something that sounds intimidating but doesn’t have to be: managing CI/CD for monorepos. Imagine your codebase as a bustling city—each project is a neighborhood, and CI/CD is the public transit system keeping everything running smoothly. But when one road closes, you don’t shut down the whole city, right? Let’s explore how to keep your monorepo efficient, scalable, and sane. Why Monorepos? (And Why CI/CD Gets Tricky 🧩) Monorepos are like a shared workspace for your projects: Pros: Unified dependencies, cross-project refactors, and streamlined collaboration. Cons: A single commit can trigger chaos if CI/CD isn’t optimized. The Challenge: Over-testing: Rebuilding everything on every change. Dependency Hell: "Wait, which service u…  ( 4 min )

Packaging Python projects into standalone executables can be incredibly useful for sharing your work with non-developers.

The In-Memory Advisor in Oracle 23ai analyzes database workloads to estimate DB-Time for various In-Memory sizes. Additionally, it can recommend which objects should be placed in the In-Memory column store. To use this feature, you must leverage the DBMS_INMEMORY_ADVISE package. The procedure for running the In-Memory Advisor is similar to the Privilege Analysis feature. To generate advice regarding In-Memory optimization, you first need to start a task and let it analyze the database workload. Once sufficient analysis has been performed, you can stop the task and review the generated report. The following sections detail the steps to generate the report: Step 1: Enable Heat Map SQL> exec dbms_inmemory_advise.start_tracking(:task_id); ORA-20000: Heat map is not enabled.

Hi, I’m Mridul Bansal. I’m 18. A first-year student at Newton School of Technology, Pune — but this isn’t about college. This is about a choice I made a few weeks ago: to become one of the top 100 AI/ML minds on the planet in the next 3 years. And I’m documenting everything. Every hour, every line of code, every mental breakdown, every rebuild. This is Day 1 of that journey. But it didn’t start today. In March, I joined offline coaching for Full Stack + AI/ML because YouTube wasn’t enough for me. I’m someone who learns best when I’m all in — environment, people, mindset. So I customized my learning path: Full Stack (MERN) My mindset shifted fast. From just wanting to stay ahead in college → to dominating my batch → to aiming at global level skill. That’s how I landed here. What I Did This Week This past week was about setting foundations — mentally, technically, and emotionally. My Weekly System (Moving Forward) Execution Stack: React.js + MongoDB coming next _ Posting Plan- _ I won’t be posting every day. I’ll post here once a week — just to keep it real and show exactly what I’ve built or learned. No fluff. Just raw execution logs, week by week. Closing Thought- I’m not doing this blog for likes. I’m writing this so that when someone 2 years from now wants to know how I did it — they won’t just see the success, they’ll see the system. No motivation quotes. No branding tricks. Just one guy documenting his rebuild. Let’s build.  ( 4 min )

As the Head of Engineering at Bacancy, I often speak with businesses that are hesitant about moving to the cloud. They understand the benefits but worry about the complexity. What if the migration disrupts operations? What if costs go out of control? What if the existing infrastructure is too rigid to support the transition? These are valid concerns. But when a company like Bajaj Finance successfully moves its core lending platform to the cloud, it sends a strong message. If they can do it, so can you. This shift was not just a technical upgrade. It was a clear business decision aimed at making their infrastructure more agile, secure, and ready for growth. Bajaj’s move demonstrates that even the most critical systems can run better in the cloud. And they are not alone. We’ve helped several…  ( 6 min )

“We version packages, sign commits, and write changelogs — but our UIs stay anonymous.” That didn’t sit right with me.

The use of yield return in C# has always been a bit of a mystery to me, but recently I’ve come to understand a bit better how it works and when it can be useful. Put simply, yield return allows you to generate values on demand as if they were part of a collection (IEnumerable), without having to manually create or populate a list. Items are returned one by one, only when needed, without storing them all in memory beforehand. Its main advantage lies in supporting lazy evaluation. Imagine you're working on a system that processes data from a large source (maybe a .csv file to be imported or even a .txt log file). In such cases, yield return can optimize memory usage, since it lets you load only one line at a time and begin processing immediately, without waiting to read the entire file. IEnu…  ( 6 min )

User experience design (UX design, UXD, UED, or XD), upon which is the centralized requirements for "User Experience Design Research" (also known as UX Design Research), defines the experience a user would go through when interacting with a company, its services, and its products. User experience design is a user centered design approach because it considers the user's experience when using a product or platform. Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions, for which is known as UX Design Research. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), and encompasses all design aspects and design stages that are around a customer's experience.  ( 3 min )

Do you see anything wrong in below image? 👀 No? 🧐 I have made a minor change do you see what I am talking about now? This is something that tripped me up recently — turns out it’s caused by a little CSS behavior called margin collapsing. 🤔 So, what is Margin Collapsing? As per MDN: The top and bottom margins of blocks are sometimes combined (collapsed) into a single margin whose size is the largest of the individual margins (or just one of them, if they are equal), a behavior known as margin collapsing. Note that the margins of floating and absolutely positioned elements never collapse.

Foi nesse contexto que percebi como a gestão de projetos deixou de ser apenas uma função organizacional e passou a ser um pilar técnico. A engenharia precisa de autonomia, mas também precisa de direção. Não adianta termos um time que domina o React, o Kubernetes ou o GitHub Copilot se os ciclos são confusos, as prioridades mudam a cada reunião e as entregas perdem consistência. Empresas como o Nubank entenderam isso cedo. Mesmo utilizando Clojure uma linguagem funcional pouco comum conseguiram escalar por apostar…  ( 4 min )

🛠️ Tired of spending hours hunting down frontend bugs? Here’s a battle-tested debugging checklist that’ll save you time, frustration, and maybe even your sanity. (Bookmark this—you’ll need it later.) 🔍 Step 1: Reproduce the Bug Consistently Before diving into code, make sure you can reliably trigger the issue. ✅ Ask yourself: Does it happen in incognito mode? (Rule out extensions) Does it occur on mobile vs. desktop? What’s the exact sequence of actions that causes it? 🚨 Pro Tip: Record the bug with Chrome’s "Recorder" (DevTools > More Tools > Recorder) to replay steps. 🛠️ Step 2: Isolate the Problem A) Check the Console First Errors? Look for Uncaught TypeError, Failed to load resource. Warnings? React hydration issues, deprecated APIs. 🚨 Pro Tip:…  ( 4 min )

I have been building a React-based video editing SDK tailored for apps that need to generate, edit, or enhance video content — especially AI-generated content like explainers, reels, and product showcases. As more AI tools pump out video content, one big pain point keeps surfacing: “How do we give users manual control over what the AI just made?” Most AI video tools can generate content — but they fall short when users want to fine-tune it. You get a video, but can’t easily: Add styled captions Adjust scenes Sync audio Edit the timeline Apply effects So I am building a toolkit that lets you embed an editing layer right into your frontend. Here’s a breakdown of what the SDK offers out-of-the-box: Media Utils Extract metadata (video, audio, images) Resize and fit media for different layouts Generate audio visualizers Extract audio from video Media Parser Convert .mov / .webm ➝ .mp4 Compress large video files Handle encoding seamlessly in the background Lambda Integration Export videos via AWS Lambda Save output directly to cloud storage (S3) Timeline Editor Trim, split, and arrange media layers Add & sync text, effects, and audio Timeline-based editing made React-friendly AI-Powered Captions Auto-generate captions from voice/video Apply styled caption themes Live Edit Canvas Drag, resize, rotate video elements Realtime sync with the timeline Live preview as you edit UI Visualizer Panel-based editor Built-in state management (with undo/redo) Effects Engine Canva-style animations: pop, flicker, fade, zoom Text effects: typewriter, staggered, bounce Visual filters for color grading & tone This SDK is ideal for: AI video generation tools (ChatGPT agents, script-to-video platforms) Social media automation apps Product marketing video builders Internal tooling for media teams Watch it in action?

Hello guys! I've been on a wile ride the past couple of months, working on something kinda stupid. Running CS:GO on the browser, yes you read that right, Its slow, janky, and held together with duct tape and hope but it runs... well its running... Back in 2023, a user made a feature request/issue to the nillerusr/source-engine repository on GitHub requesting that there should be support for compiling to Emscripten and WebAssembly platforms. I'd never seen it during that time, but I had the same thought back then, I wanted to play Half-Life 2 on my crappy chromebook. I was inspired by the Xash3D port for Emscripten, I tried to do it back then, but I was a script kiddie (Before, not now), and I didn't know how to code.

Hey everyone, Efficiency Hub, a curated directory of productivity tools built by indie makers. It’s not a huge launch, but it’s a real one. I’ve made $25 so far from my first sponsored app, and what’s more exciting is that people are actually using it, submitting their apps, sharing screenshots, even paying to highlight their tools. I gathered a bunch of feedback from the Reddit community while building it, trying to keep the vibe as authentic and helpful as possible. No bloated AI magic, no VC hype, just a place to showcase solid tools made by focused builders. Some things I did intentionally: Made the submission form super lightweight with optional paid slots Prioritized clarity and trust (you see who made what, and why) Designed it for solo devs and small teams, not big startups If you’re working on something in the productivity space, feel free to submit it. Would love to feature more indie tools that help people get things done without the fluff. Happy to answer questions on setup, pricing, tech, or anything else.  ( 3 min )

In recent times, with Cursor, lovable, and 101 other AI tools, I see many junior developers jumping on the AI bandwagon and just using generators to scaffold code. I also see a great deal of fear in the industry as well, fear that AI will take our jobs. The standards are becoming tougher, it's no longer enough just to know HTML+CSS and a backend language. To survive in modern times, you need to have a deeper understanding of programming and the tools in general. By attending a BootCamp and learning how to build something in [enter framework here], you most certainly can get a job in a few weeks or months' time. However, if you want to survive in the industry for 10+ years and beyond, you need to equip yourself with skills beyond what the market wants today. You should be able to pivot based on demand and grow as the industry changes. To do this, the best place to start is not the docs of [enter framework here]. Rather, it's computer science. Most of the industry has changed a lot in the past 20 years, but actually, the core concepts haven't changed much; thus, learning computer science will help you develop a strong, deeper understanding of how things work and therefore allow you to become a better problem solver. Having been around the block for more than 15 years, I have worked on many, many different problems of varying complexities. Many of these required me to draw on advanced programming and networking knowledge. Anyway, long story short 🙃 I'm working on a series of articles to go deeper into concepts we often ignore as web developers. My goal is to help upskill you into a more complete engineer (and also improve my knowledge too). here's the first article - understanding bits and bytes.  ( 3 min )

By Dhanian (@e_opore) Coding is more than just typing lines into an editor—it’s a craft, a puzzle, and for many of us, a deeply personal journey.

Both have shaped me as a developer. One grounds me, the other frees me. Today, I’m sharing their magic, quirks, and how you can find your rhythm between the two. Plus, I’ll introduce a resource I built to help you level up your style—available now on Gumroad.

In economics, Gresham's Law teaches us that "bad money drives out good." A powerful analogy, and surprisingly pertinent, permeates the daily life of software engineering: low-quality code tends to supplant well-crafted code. In a software development ecosystem often pressured by tight deadlines and continuous deliveries, the temptation to opt for quick and superficial solutions ("bad code") can become overwhelming. Although these approaches may offer short-term gains, they insidiously undermine the health and sustainability of our projects.

Read the full story here → What 117 Days of Reflection Taught Me About Crafting Code That Endures For 117 days, I've been writing a short reflection every morning. At first, it was just a quiet ritual. A way to center myself before diving into code. But over time, it became something else. I started noticing patterns in how I approached problems, how I rushed when I should have paused, and how often I worked around I should have worked through it. These reflections reminded me of the kind of developer I want to be. One who builds with care and writes code that stays strong when things get messy. Here are a few lessons that stuck: Each day, I pair a short insight with a quote from the Stoics. Not to sound wise, but to stay grounded.

🏹 Null Safety in Kotlin Dodging the Null Pointer Exception, the Kotlin way🤓🤓 ➤ Concept of Strict Null Safety in Kotlin • Safe Call Operator ( ?. ) in Kotlin ( ?: ) in Kotlin ( !! ) in Kotlin. Kotlin allows to store “Null” values in a variable. In Kotlin, the variables can be made of Null types by just adding a “?” symbol to the right side of the data type. A nullable type variable means it can also hold “Null” as a value in it. A non-nullable type variable means that it can not hold “Null” as a value in it. The safe call operator is simply a question mark followed by a dot ( ?. ) The safe call operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the left-hand side of the operator is null, then it will return null value. If the left-hand side of the operator is not null, then it will return the result of the right-hand side expression. The elvis operator is represented by a question mark followed by a colon ( ?: ) The elvis operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the first operand is not null, then this operand will be returned by the elvis operator. If the first operand is null, then second operand will be returned by the elvis operator. The Not Null Assertion is represented by a double exclamation mark (!!) The Not Null Assertion in Kotlin, is another tool to deal with nullity. This operator explicitly casts nullable variables to non-nullable variables.  ( 3 min )

"The main motivation, the original motivation for (creating) Lean was in software verification, right? I mean, Z3 was very popular at bug finding, for bug finding at Microsoft, was very influential there. But (for) Lean the goal was, can we make the same, have the same success of software verification? We went to a very strange path. I mean, having impact in mathematics that we never dreamt of. But the goal in both cases is like we, both in software mathematics and in AI, today rely on manual review, partial testing. A mistake in a theorem can be catastrophic, invalidating the whole result. The same thing (happens) for a critical piece of software, right?

Before you hand in your notice because you’re “bored” let’s talk about what’s really going on out there. Introduction: you’re not stuck you’re just not in a dumpster fire You ever scroll through LinkedIn, see someone posting “just accepted a new role at some stealth-mode AI unicorn,” and feel like you’re wasting away in your stable, semi-boring software job? Yeah same. But here’s the thing: that quiet job you’re lowkey resenting might be the best thing you’ve got in 2025. Welcome to the post-hype collapse of the tech job market. Layoffs are still happening. Job applications are ghost towns. And even if you do make it past the resume filter, chances are your recruiter got laid off last week. This isn’t fearmongering. It’s just the reality seasoned devs are seeing (and what some brave souls …  ( 9 min )

Exploring the bugs, bloat, and burnout behind today’s software and why it’s not entirely your fault. Introduction: welcome to the software multiverse of madness Let’s be real: software in 2025 feels like it’s stuck in a boss fight it can’t win. Every time you open your favorite app, something’s changed and not always for the better. Your battery drains faster, the “new improved” UI hides buttons you used daily, and the performance? Feels like it’s running on a toaster powered by anxiety. You’re not alone. Developers are tired. Users are mad. Product managers are aggressively optimistic. And somewhere in the middle of this chaos, software ships whether it’s ready or not. So the question lingers: Is software actually getting worse… or are we just becoming more aware of its flaws? This artic…  ( 10 min )

Starting tomorrow, I'm grinding through 100 days of raw backend development—no tutorials, no handholding. Just Node.js, PostgreSQL, and the ugly realities of building systems that scale. The Challenge 100 days, 100 commits: Atomic backend projects pushed to https://github.com/joshylak/100-backend-projects Tech Stack: Sample Battle Plan Phase 1: Core Systems (Days 1-30) Day 1: Bare-metal HTTP server (no Express) Day 12: Connection pool leak detector Day 23: JWT blacklist with Redis Lua scripts Phase 2: Pain Points (Days 31-70) Day 37: N+1 query exterminator Day 45: Distributed deadlock simulator Day 63: Postgres failover with pg-rewind Phase 3: Bloody Edge Cases (Days 71-100) Day 82: WebSocket flood attack mitigator Day 91: CTE-based RBAC permission tree Day 100: Zero-downtime schema migrations Why This Matters No ORMs allowed: Raw SQL or bust.

Real-world insights from the trenches of senior engineering no fluff, no gatekeeping, just hard-earned truths Introduction Let’s be honest: the internet is overflowing with feel-good developer advice. “Write clean code.” “Use version control.” Cool story, bro. But what happens when you’re neck-deep in a spaghetti codebase with legacy bugs older than your GitHub account? That’s where real lessons begin. I was lucky and unlucky enough to work under a principal engineer who didn’t sugarcoat anything. Think senior dev meets Jedi master, minus the lightsaber and plus a ton of passive-aggressive code reviews. He didn’t just teach me how to write better code he rewired how I think as a developer. This isn’t another list of beginner tips. These are 15 survival rules forged in production fires, arc…  ( 13 min )

After backlash, a fork, and a community exodus, Redis is rolling out v8 open source again, and stacked with features. But is it too little, too late? Introduction A few months back, we talked about the quiet revolution happening in the in-memory data world how Valkey, the community-led fork of Redis, was suddenly gaining traction after Redis Inc. decided to lock the doors on full open source. If you missed that breakdown, catch up here: Why Redis is losing friends and Valkey is gaining them But now, in a dramatic plot twist worthy of a season finale, Redis 8 is here, and it’s back with something most devs didn’t expect: a full return to open source under the BSD license. Not just that Redis 8 ships with real upgrades, not just a PR apology. Faster I/O threads, memory optimizations, smarter…  ( 8 min )

“Same title. Same job. Very different outcomes.” If you've ever worked on a dev team, you’ve probably noticed it: not all developers with the same title operate at the same level. Some juniors write better code than mids. Some seniors… well, are just loud middles. So what actually separates a junior developer from a mid-level or senior engineer? Is it years of experience? Code quality? Confidence in meetings?

As engineers, we use transactions all the time — BEGIN, COMMIT, and maybe a rollback if things go south. But recently, I realized I hadn’t truly internalized what makes those transactions reliable. That curiosity led me to revisit the ACID properties — a foundational concept we all learn early on but rarely pause to deeply understand. What started as a quick refresher turned into a deep dive into atomicity, consistency, isolation, and durability, and how real databases like PostgreSQL and MySQL implement them. Along the way, I discovered that one core mechanism — the Write-Ahead Log (WAL) — is key to both Atomicity and Durability, playing a foundational role in keeping transactions safe and recoverable. In this first part of a multi-part series, I’ll walk through what each property means, …  ( 5 min )

When working with Angular and RxJS, takeUntil is a common operator for unsubscribing from observables, especially in component lifecycle management. However, if you're using takeUntil incorrectly with higher-order mapping operators like mergeMap, switchMap, concatMap, exhaustMap, you may still end up with memory leaks. A common mistake is placing takeUntil before a higher-order operator in your observable pipeline. This seems logical, but it doesn't always behave as expected. When takeUntil is upstream of a higher-order operator, it won't effectively unsubscribe the inner subscription created by that operator. this.counterB$.pipe( takeUntil(this.destroySubject), mergeMap((value) => this.counterA$) ).subscribe(...); In the example above, the outer observable (counterB$) is unsubscribed…  ( 4 min )

GO or GOlang Introduction Go(or GoLang) is a popular low-level programming language developed by Google in 2007. And that's what we are going to cover in this blog. What is GO? How was it developed? Why should you consider learning GO? So let's not waste our time and jump in. GO is a general-purpose programming language. It is statically typed and compiled. It is known for its simplicity of syntax and a better developer experience than other programming languages in the same niche, like: C C++ Rust A statically typed language is one where the type checking is completed at compile time, meaning the data type of each variable (string, integer, etc.) is known before the program runs and cannot be changed afterwards. Many people get confused and think that GO is both statically and dynamically typed because: x := 2 //Dynamically declared (GO's Type interface decides the type). var y int = 4 //Statically declared. Both ways can be used to declare variables in GO. But then why do we say it's statically typed? Because in a statically typed language like GO, you cannot do: x := 2 and then x = "two". Doing this will cause a compilation error. But in dynamically typed languages like JavaScript, you can do the same thing as x = 2 x = 'two' console.log(x) And it will work fine. GO was developed by Google in 2007. The designers wanted to address the issues they felt with the language they used at that time, but keep their useful characteristics. Go was publicly announced in November 2009, and the first version was released in 2012. Now, this language is actively used in the world. It’s Simple and easy, unlike Rust, C++, and C. First Class Concurrency Performance Proven Track Record + Job Demand And that's why you should prefer learning GO.

The other night, I was talking about meta programming to other developers, and at one point someone asked how macros could be used to do meta programming. They were probably thinking about C type of macros, which are powerful but are just text processor tools. Using macros you could have the following code: double Compute() { // doing something return result; } and transform it into: double Compute() { if (_cache.GetValue(out var result) return result; // doing something _cache.SetValue(result); return result; } They are a tool to manipulate code, with code. It allows one to write generic code and have the compiler do the heavy lifting and monomorphize your code. What's meta programming?

Attention je n’ai pas dit qu’il ne faut rien faire ! Je veux surtout que vous compreniez la faille pour être en mesure de la corriger efficacement. Comme toujours, vous pourrez télécharger les exemples et tester chez vous pour mieux comprendre comment ça marche. — Chapitres — 00:00 Intro Liens : L’article de la faille : https://www.wiz.io/blog/ingress-nginx-kubernetes-vulnerabilities https://docs.k3s.io/installation/packaged-components https://developer.hashicorp.com/vagrant https://docs.nginx.com/nginx-ingress-controller/ https://nginx.org/en/docs/http/ngx_http_core_module.html#client_body_in_file_only  ( 3 min )

In early 2025, I realized something uncomfortable: I was spending hours every day switching between tabs, endlessly scrolling, and jumping between distractions — and I didn’t even realize how often it was happening. Like many developers and students, I use a computer all day. But I noticed a pattern of compulsive behavior that wasn’t productive. I wasn’t just “working online.” I was switching contexts 50+ times an hour — email, YouTube, Reddit, docs, social media, GitHub… repeat. I wanted to understand my dopamine loops — those invisible triggers and habits that push me to seek micro-hits of pleasure instead of focusing on deep work. That’s why I started building Dopamine Tracker — a minimal, privacy-focused tool that: tracks online behavior via a browser extension, stores it in a Supabase backend, and visualizes patterns through a React dashboard. It’s not about guilt or blocking websites — it’s about insight and agency. Right now, the extension logs: Active tab time App switches and focus changes Time-of-day usage Top “dopamine drivers” (based on frequency + context) Everything is stored locally in local storage as for the alpha stage. I’m sharing this journey to: document the technical process (React, Supabase, browser APIs), reflect on design choices and architecture, connect with others working on similar problems. If you’ve ever found yourself working but not really working — this project might speak to you. In the coming weeks, I’ll share devlogs on: implementing dopamine tracking and scoring algorithms designing the extension UI, building the analytics dashboard, Thanks for following along. Let’s see where this goes. Stay mindful, stay focused. — Pietrell  ( 3 min )

Introduction The next generation of AI assistants is here — and they’re not just smarter, but far more connected. At the heart of this evolution lies the Model Context Protocol (MCP), an open standard introduced by Anthropic in November 2024. Much like how REST transformed the web by standardizing communication between services, MCP aims to do the same for AI by enabling seamless, scalable access to data and tools across platforms. Why We Needed MCP Despite their sophistication, most AI models operate in isolation. Critical information is often trapped in disconnected silos — internal databases, legacy systems, and proprietary tools. Integrating AI assistants with these sources required bespoke connectors, resulting in the infamous N×M integration problem: every new model needed custom cod…  ( 6 min )

Understanding Object References in JavaScript Have you ever changed something you thought was a separate copy, only to find you messed up the original data too? Yeah, that happens a lot if you don't get how JavaScript handles different kinds of copying; deep copy vs shallow copy. JavaScript has these two main ways it thinks about data: by value and by reference. Simple stuff like numbers, strings, booleans, null, and undefined are value types. When you copy them, JavaScript just makes a whole new one. A separate thing entirely. Changing the new one never affects the old one. let a = 10; let b = a; // b gets a copy of the value 10 b = 20; console.log(a); // Output: 10 (a is unchanged) However, objects, arrays, and functions are reference types. When you assign one variable to another, yo…  ( 10 min )

This is a basic Go lang project that shows your age if you know your birth year. In this, you have to input your birth year, and it will take the current year automatically. By using the formula Current Year - Birth Year, it shows your current age. This project is mainly intended to learn how to containerize an application. It is not a Go-focused project but mainly Docker-focused instead. A Dockerfile will be created to build a Docker image and run it inside a container. Once containerized, the application can be run easily using Docker commands on any system that supports Docker, regardless of the host environment. This helps demonstrate the power of containerization and the portability it brings to software development. The project will also serve as a base to practice Docker fundamentals like: -> Writing a Dockerfile -> Building a lightweight image for a Go application -> Running the image as a container -> Understanding how to manage input/output inside the container Overall, this project provides a practical, beginner-friendly example of containerizing a simple application — making it a great starting point for learning Docker and DevOps workflows.

Everyone tells you how to write perfect code. But no one tells you how easy it is to mess things up, especially when you're just starting out. 1. Writing Code Without Planning Anything: I jumped straight into coding because I was too excited. The Result: Now, I sketch out a quick plan, even 10 minutes of thinking saves hours of debugging. 2. Copy-Pasting Stack Overflow Without Understanding: I copied a solution that worked—until it didn’t. The Result: I still use Stack Overflow, but I make sure I understand every line I paste. 3. Ignoring Git Until the Last Minute: I lost an entire day’s work because I forgot to commit. The Result: I commit after every major change and push regularly. Git is now my safety net. 4. Not Reading the Documentation: I wasted hours searching for answers that were literally in the first paragraph of the docs. The Result: First I read the docs, then surf the internet for information. Even the order of this matters. 5. Overengineering Everything: I tried to build “the perfect solution” with 10 extra features I didn’t need. The Result: Build version 1 very simple. Improve later. Launch ugly, improve fast. 6. Not Asking for Help: I stayed stuck on a bug for 3 days because I didn’t want to “look dumb” by asking help. It was a terrible mistake. The Result: I now ask questions early—online, Discord, dev forums. No shame in learning. 7. Testing Code in Production: I pushed code live without testing. The Result: I test locally, then deploy to staging, then go live. Never gonna skip testing again. Final Thoughts: Which one hit you the hardest? Drop it in the comments.  ( 4 min )

What are Push Notifications ? Push notifications are messages sent from an app or website to a user's device, even when the app or site isn’t actively open. They appear as pop-up alerts, banners, or notification icons on devices like smartphones, tablets, and computers. The mechanism with which these "Push Notifications" work is usually the use of some sort of background processes, these processes maintain a persistent connection with the designated "Push Server" depending on their device (in the case of Native Push) or their navigator (in the case of Web Push).

Hello! 👋 I’m working on a solo project to build a no-code quantitative trading backtesting platform — a tool that enables users to visually create trading strategies, backtest them on historical market data, and analyse their performance. I know nothing about Quantitative trading but I would like to learn about it just for fun. My own personal goal for this project is ultimately to learn more about quant and to try building a full project by myself. The reasoning behind making a visualiser in particular is because I find that visualisers are really helpful for understanding new concepts, the issue with quantitative trading however, is that there's a big learning curve and the majority of resources are hidden behind a paywall, making just learning the basics quite difficult without diving …  ( 4 min )

In software design, a God Object (or God Class) is a class that knows too much or does too much. It's a common code smell that tends to emerge as a system evolves without proper boundaries. A God Object violates the Single Responsibility Principle by taking on multiple responsibilities. It typically centralizes control and knowledge of many parts of a system—handling tasks that should be delegated to other specialized components. Even experienced developers can fall into this trap, usually due to: Moving fast: Prioritizing speed over modularity in early stages. Avoiding perceived complexity: Putting logic in one place “for convenience.” Fear of breaking things: As the class grows, refactoring becomes scarier. Lack of clear ownership boundaries: Developers aren't sure where logic belongs. L…  ( 4 min )

Believers say: 易 “Thoughts become things.” Let’s bring in Instagram, Facebook, or YouTube: Don’t like a post? No problem. Just pause for a few seconds, and BAM — the algorithm picks it up. Now your feed is filled with related posts, ads, and suggestions. It feels like magic. But it’s not. Every interaction you make: Scroll Click Pause Comment …is stored, tracked, and processed.

I've created a "tune API" for the next version of VarMQ. Essentially, "Tune" allows you to increase or decrease the size of the worker/thread pool at runtime. For example, when the load on your server is high, you'll need to process more concurrent jobs. Conversely, when the load is low, you don't need as many workers, because workers consume resources. Therefore, based on your custom logic, you can dynamically change the worker pool size using this tune API. In this video, I've enqueued 1000 jobs into VarMQ, and I've set the initial worker pool size to 10 (the concurrency value). Every second, using the tune API, I'm increasing the worker pool size by 10 until it reaches 100. Once it reaches a size of 100, then I start removing 10 workers at a time from the pool. This way, I'm decreasing and then increasing the worker pool size. Cool, right? VarMQ primarily uses an Event-Loop internally to handle this concurrency. This event loop checks if there are any pending jobs in the queue and if any workers are available in the worker pool. If there are, it distributes jobs to all available workers and then goes back into sleep mode. When a worker becomes free, it then tells the event loop, "Hey, I'm free now; if you have any jobs, you can give them to me." The event loop then checks again if there are any pending jobs in the queue. If there are, it continues to distribute them to the workers. This is VarMQ's concurrency model.  ( 3 min )

In modern React development, user interactivity is everything.

When people hear "software engineer," the first image that pops into their mind is someone furiously typing code, probably in a dark room with six monitors and a cup of cold coffee. But is that all there is to it? Not even close. In this post, let’s explore what it really means to be a software engineer — beyond the code. Being a great software engineer isn’t just about knowing 12 different JavaScript frameworks. It's about understanding problems and communicating solutions. Can you explain a complex bug to your product manager in simple terms? Can you write clear, helpful documentation? Can you give constructive feedback in code reviews? 💡 If you're not improving your communication skills, you're limiting your growth. You’ll often face challenges that have nothing to do with code: Ambiguous requirements Legacy systems with no documentation Interpersonal team conflicts Sometimes, you spend more time on Slack than in VS Code. And that’s okay. That’s part of the job. You don't just learn programming languages — you learn people, processes, and priorities. The most successful engineers I've met are not the ones who knew everything — but the ones who kept learning every day. Burnout is real. Sleep deprivation doesn’t make you a hero. Take breaks. Set boundaries. Eat lunch away from your screen. Because your brain is your best asset — and it needs rest to work its magic. Software engineering is a journey — and the code is just one part of it. The next time someone asks you what you do, don’t just say "I write code." Because that’s what you really do. 💬 What’s something you've learned outside of code that made you a better developer? Drop your thoughts below — let's talk!  ( 4 min )

My Journey with RSI A story about my experience with finger pain and how I overcame it. Every situation is different, but I hope this helps or informs you. The first half of the post is a weekly account of the experience and my attempts to fix this bug. The second half is the solution I found and the lessons learned. TLDR: If you want to jump straight to the climax and resolution, skip to The worst week - and the turning point (week 13) Trigger condition: Was walking to work in 7c winter mornings without wearing gloves or a jacket, followed by typing right afterward. At this time, I was writing 29 ESLint rules & accompanying tests (compared to regular coding, this involves more typing and fewer breaks for thinking). Typing for 9-12 hours a day, 7 days a week. In retrospect, I should have s…  ( 12 min )

Let’s break down each type of dependency in package.json in detail: Dependencies ("dependencies") These are the essential packages required for your project to run in production. They are installed automatically when you run npm install or yarn install. Example: If you're building a React application, react and react-dom would be dependencies. Defined like this in package.json: "dependencies": { "react": "^18.0.0", "redux": "^4.1.0" } When you deploy your application, these packages are included. DevDependencies ("devDependencies") These packages are only needed during development (e.g., testing tools, linters, build tools). They won’t be included in the production build. Example: Testing frameworks like jest or bundlers like webpack. Installed with: npm instal…  ( 3 min )

Nos últimos dias venho estudando a linguagem Go e me deparei com um assunto que achei muito interessante: os operadores bit a bit. Como eu ainda não os conhecia bem, resolvi compartilhar o que aprendi com vocês. Além dos operadores de comparação já conhecidos && (E), || (OU), > (Maior que), etc., Golang possui assim como em outras linguagens os operadores bitwise, que são representados pelo símbolos &, |, ^, >>, representação binária final fmt.Println("a> - deslocamento à direita (right shift) Desloca os bits de a para a direita, descartando os bits da direita. // a = 0110 // a = 0110 >> 2 // a = 01 // a = 0001 -> representação binária final fmt.Println("a>>2: ", a>>2) // 1 E aí, gostou?

Why use pnpm Faster then npm More dist-efficient (uses symlinks and a content-addressable store) Strict by default (prevents dependency hoisting issues) pnpm npm install -g pnpm pnpm init This command creates a package.json file. Add a package: pnpm add Add a dev dependency: pnpm add -D Example: pnpm add react pnpm add -D typescript ts-node In package.json, define scripts like this: { "scripts": { "start": "node main.js", "dev": "vite" } } Then run pnpm start pnpm dev pnpm install (Shortcut: pnpm i) Remove a package pnpm remove Update packages pnpm update List installed packages pnpm list pnpm: pnpm creates a pnpm-lock.yaml instead of package-lock.json. If you're using a monorepo, pnpm handles it differently (via workspaces). You might want to delete node_modules and package-lock.json before switching to avoid conflicts: rm -rf node_modules package-lock.json pnpm install  ( 3 min )

1931. Painting a Grid With Three Different Colors Difficulty: Hard Topics: Dynamic Programming You are given two integers m and n. Consider an m x n grid where each cell is initially white. You can paint each cell red, green, or blue. All cells must be painted. Return the number of ways to color the grid with no two adjacent cells having the same color. Since the answer can be very large, return it modulo 109 + 7. Example 1: Input: m = 1, n = 1 Output: 3 Explanation: The three possible colorings are shown in the image above. Example 2: Input: m = 1, n = 2 Output: 6 Explanation: The six possible colorings are shown in the image above. Example 3: Input: m = 5, n = 5 Output: 580986 Constraints: 1 <= m <= 5 1 <= n <= 1000 Hint: Represent each colored column by a bitmask based on each cell co…  ( 26 min )

I'm not focused on frameworks as much as I am on structure. I think in connections, constraints, rhythms, and failure points. I use React like I use poetry — to shape space. This is probably not what you're used to, but it's why I'm here. Also, I believe bigger areola ratios make for better ergonomic metaphors. Ask me about it.  ( 3 min )

Understanding DNS: How Domain Names Become IP Addresses In our previous blog post, we covered domains and their various aspects. Now, let's dive deeper into DNS (Domain Name System) - the backbone of internet navigation. DNS, or Domain Name System, is essentially a translator for the internet. Its primary function is simple yet crucial: it converts human-friendly domain names (like example.com) into machine-readable IP addresses that computers use to identify each other. Without DNS, you'd need to memorize numeric IP addresses instead of easy-to-remember domain names. Before we explore how DNS works, let's clarify two important roles that make the domain system possible: A registry is an organization that manages a specific top-level domain (TLD) For example, Verisign manages the .com an…  ( 8 min )

Key points: Bitcoin’s rally to $105,980 has traders predicting new all-time highs this week. Traders lift their end-of-year Bitcoin price targets to $200,000 based on technical factors and institutional investor adoption.  Bitcoin (BTC) has been stuck in a narrow range for the past few days, but the rally above $105,500 on May 18 increases the possibility of an upside breakout. Popular trader Alan said in a post on X that Bitcoin could soar to $116,000 early next week. Another bullish voice was that of Bitwise chief investment officer Matt Hougan. While speaking to Cointelegraph, Hougan said that a supply shock due to increased institutional demand could propel Bitcoin to $200,000 by the end of 2025. He expects seller exhaustion to occur at the $100,000 level. Crypto market data daily …

Attorneys for Tornado Cash developer Roman Storm filed a motion asking the court to reconsider the motion to dismiss the case due to the prosecution withholding exculpatory evidence in the form of communications with the Financial Crimes Enforcement Network (FinCEN) dating back to 2023. According to a May 16 letter from Storm's attorneys to Judge Katherine Polk Failla, the FinCEN documents show that non-custodial crypto mixers do not fall under the legal definition of a "money transmitting business" and that prosecutors have known this since at least 2023. Despite having knowledge of the FinCEN guidance on crypto mixers, state prosecutors still proceeded with cases against the Samourai Wallet developers and Tornado Cash, the attorneys alleged. Letter sent by Roman Storm’s attorneys to Judg…

Telegram founder Pavel Durov said he rejected pressure from a European Union (EU) country to censor political content on the social media platform ahead of the May 18 presidential elections in Romania. According to Durov, a Western European government, which he hinted at with a baguette emoji, approached the platform and requested it censor conservative voices, which he flatly denied. Durov wrote in a May 18 Telegram post: "You can't 'defend democracy' by destroying democracy. You can’t 'fight election interference' by interfering with elections. You either have freedom of speech and fair elections — or you don’t. And the Romanian people deserve both." The Telegram founder is an ardent defender of free speech, who is highly regarded in the crypto community for his stances on freedom of exp…

Crypto industry executives are beefing up personal security and demanding more bodyguard services in response to a recent string of kidnapping and ransom attempts worldwide — particularly in France — targeting investors and professionals in the sector. According to a Bloomberg report, Infinite Risks International, a private security firm based in Amsterdam, Netherlands, is seeing more inquiries into bodyguard services and more long-term clients signing up for a private security detail. Additionally, French law enforcement officials recently announced enhanced security measures for crypto entrepreneurs and investors, following at least three separate kidnapping incidents so far in 2025. The measures include security briefings and expedited access to police lines in the case of emergencies …

Opinion by: Igor Mandrigin, co-founder and CTPO of Gateway.fm Every couple of weeks, it seems another layer 2 rolls out, much to the chagrin of some Web3 industry commentators who are concerned about fragmentation. A recent Gemini Institutional Insights report actually noted how a new Ethereum L2 solution is launched approximately every 19 days. In response to the seemingly endless conveyor belt of new zkEVMs and optimistic rollups coming to market, the chorus of criticism continues to grow louder: “This is definitely the saturation point, no more chains are needed.” Some of the most outspoken critics of L2s argue that L2s are redundant, but this is narrow thinking. In many ways, the idea that creating new L2s should be slowed down is like arguing that there were too many websites in 1998.…

Economist and author of The Bitcoin Standard, Saifedean Ammous, has weighed in on the ongoing debate over spam inscriptions on the Bitcoin network, suggesting he would “throw in a few sats” to fund a full-time developer focused on making Bitcoin spamming more difficult and expensive. Ammous made the remarks in response to a thread initiated by the pseudonymous developer GrassFedBitcoin, who called for Bitcoin Core to merge pull request #28408, which would enable node operators to filter inscriptions more easily. According to GrassFedBitcoin, the lack of inscription filtering tools contributes to unnecessary blockchain bloat and undermines Bitcoin (BTC)’s role as a monetary protocol. “No one running a node wants to relay inscriptions,” he wrote, arguing that the OP_RETURN limit increases we…

Retired artist Ed Suman lost over $2 million in cryptocurrency earlier this year after falling victim to a scam involving someone posing as a Coinbase support representative. Suman, 67, spent nearly two decades as a fabricator in the art world, helping build high-profile works such as Jeff Koons’ Balloon Dog sculptures, according to a May 17 report by Bloomberg. After retiring, he turned to cryptocurrency investing, eventually accumulating 17.5 Bitcoin (BTC) and 225 Ether (ETH) — a portfolio that comprised most of his retirement savings. He stored the funds in a Trezor Model One, a hardware wallet commonly used by crypto holders to avoid the risks of exchange hacks. But in March, Suman received a text message appearing to be from Coinbase, warning him of unauthorized account access. After …

United Kingdom crypto companies will need to collect and report data from every customer trade and transfer beginning Jan. 1, 2026 as part of a broader effort to improve crypto tax reporting, the UK government said. Everything from the user’s full name, home address and tax identification number will need to be collected and reported for every transaction, including the cryptocurrency used and the amount moved, the UK Revenue and Customs department said in a May 14 statement. Details of companies, trusts and charities transacting on crypto platforms will also need to be reported. Failure to comply or inaccurate reporting may incur penalties of up to 300 British pounds ($398.4) per user. The UK Revenue and Customs department said it would inform companies on how to comply with the incoming …

Hong Kong police arrested 12 people involved in a cross-border money laundering scheme that relied on crypto and over 500 stooge bank accounts to launder HK$118 million ($15 million), local news outlets reported. The syndicate was dismantled on May 15, resulting in the arrest of nine men and three women in mainland China and Hong Kong. The suspects allegedly recruited others to open bank accounts to receive proceeds from fraud cases, which were then converted into crypto at crypto exchange shops to launder the illicit funds, Hong Kong Commercial Daily reported on May 17. The criminal organization rented a residential unit in the Hong Kong neighborhood of Mong Kok to plan and carry out its money laundering activities. Of the $15 million laundered, more than $1.2 million was linked to 58 re…
